shibs Posted March 26, 2015 Share Posted March 26, 2015 I am going to insure my 90 Winni v6 and drive home on the weekend to work on it. Little bit of background, I bought this 3 years back and it sat all three years. Tranny rebuilt, new distributor, wires, plugs, had the head gasket recall done (I am going to swing by toyo first thing tomorrow), new tires. new a/c, 1. Rear axle - Diffy - I am going to drain and fill with syn gear oil Spray the spare tire winch with wd40 and air up all the tires per sticker BEHIND the driver seat 2. Any linkage or grease points on the truck? 3. lube the locks all around and door hinges 4. Drain, fill, drain and fill Radiator with green long life low silicate antifreeze. Or should I spend the $15 and get zerex? 5. Wash engine bay with simple green 6. flush brake fluid 7. check heater core hoses and rad hoses. 8. I am running a bit rich, is my 89 chassis ODB II compliant? how do I go about narrowing down the problem? 9. New flowmaster muffler (have on hand I had bought for my 90 camry with 3vzfe, nearly 10 years back) if I can find a shop for reasonable $$$. 10. vacuum clean entire toyo, chuck all carpets, 11. Reupholster captains chair - anybody do this, how much $$ did ya hafta pay? 12. Replace stereo and speakers in cab, are there speakers anywhere else in the camper? 13. Do I have to have a coach battery? Quote Link to comment Share on other sites More sharing options...
shibs Posted March 26, 2015 Author Share Posted March 26, 2015 Also, 14. Do I have to repack the front wheel bearings? or just check them? Quote Link to comment Share on other sites More sharing options...
Derek up North Posted March 26, 2015 Share Posted March 26, 2015 OBD2 only began in 1996. I'm afraid you're not even OBD1. Quote Link to comment Share on other sites More sharing options...
zero Posted March 26, 2015 Share Posted March 26, 2015 If you want to diagnose a fuel-injection related issue, you need to jump the correct terminals in the ECM and then interpret the light blinks for trouble codes. Quote Link to comment Share on other sites More sharing options...
shibs Posted March 26, 2015 Author Share Posted March 26, 2015 Thanks Derek / JDE, A quick search revealed this: TE1 and E1 need to be jumped for it to flash the code, so it is similar to my 88 mazda. Now I have to look for the error codes and full instructions. Quote Link to comment Share on other sites More sharing options...
shibs Posted March 26, 2015 Author Share Posted March 26, 2015 is this it? For those wondering about the difference between checking the OBDI engine light and DIAG mode... just read. Basically you connect TE1, TE2 and E1. DIAGNOSIS SYSTEMDESCRIPTIONThe ECM contains a built−in self−diagnosis system by whichtroubles with the engine signal network are detected and a malfunctionindicator lamp on the instrument panel lights up.By analyzing various signals as shown in the later table (Seepage EGT−14 ) the Engine Control Module (ECM) detects systemmalfunctions relating to the sensors or actuators.In the normal mode, the self−diagnosis system monitors 21(California specification vehicles) or 18 (Other than Californiaspecification vehicles) items, indicated by code No. as shown inEGT−14. A malfunction indicator lamp informs the driver that amalfunction has been detected. The light goes off automatical−ly when the malfunction has been repaired. But the diagnostictrouble code(s) remains stored in the ECM memory (except forcode Nos. 16 and 53). The ECM stores the code(s) until it iscleared by removing the EFI fuse with the ignition switch off.The diagnostic trouble code can be read by the number of blinksof the malfunction indicator lamp when TE 1 and E 1 terminalson the DLC2 or data link connector 1 are connected. When 2 ormore codes are indicated, the lowest number (code) will appearfirst.In the test mode, 12 (California specification vehicles) or 9(Other than California specification vehicles) items, indicated bycode No. as shown in EGT−14 are monitored. If a malfunction isdetected in any one of the .systems indicated by codeNos. 13, 21, 22, 24, 25, 26, 27, 28, 31, 32, 41 and 71(California specification vehicles) or 13, 21, 22, 24, 25, 28, 31,32 and 41 (Other than California specification vehicles) theECM lights the malfunction indicator lamp to warn the technicianthat malfunction has been detected. In this case, TE2 andE1 terminals on the DLC2 or data link connector 1 should beconnected as shown later. (See page EGT2−12)In the test mode, even if the malfunction is corrected, the malfunctioncode is stored in the ECM memory even when the ignitionswitch is off (except code Nos. 43 and 51). This also appliesin the normal mode. The diagnostic mode (normal or test) andthe output of the malfunction indicator lamp can be selected byconnecting the TE 1, TE2 and E 1 terminals on the data link connector1 or DLC2, as shown later.A test mode function has been added to the functions of theself−diagnosis system of the normal mode for the purpose of detectingmalfunctions such as poor contact, which are difficult todetect in the normal mode. This function fills up the self−diagnosissystem. The test mode can be implemented by the technicianfollowing the appropriate procedures of check terminal connectionand operation described later. (See pageEGT2−12) 3VZ−FE ENGINE TROUBLESHOOTING − DIAGNOSIS SYSTEMEGT2−10Diagnosis Inspection (NormalModelMALFUNCTION INDICATOR LAMPCHECK1. The malfunction indicator lamp will come on when the ignitionswitch is turned ON and the engine is not running.HINT: If the malfunction indicator lamp does not light up,proceed to troubleshooting of the combination meter(See page BE−53).2. When the engine is started, the malfunction indicator lampshould go off.If the light remains on, the diagnosis system has detecteda malfunction or abnormality in the system.DIAGNOSTIC TROUBLE CODE CHECK1. Turn ignition switch on.2. Using SST, connect terminals between TE1 and E1 ofDLC2 or data link connector 1.SST 09843−18020As an example, the blinking patterns for codes; normal,12 and 31 are as shown on the illustration.4. Check the details of the malfunction using the diagnostictrouble code table on page EGT−14 .5. After completing the check, disconnect terminals TE 1 andEl, and turn off the display.HINT: In the event of 2 or more malfunction codes, indicationwill begin from the smaller numbered code and continuein order to the larger.3. Read the diagnostic trouble code from malfunction indicatorlamp.HINT: If a diagnostic trouble code is not output, check theTE 1 terminal circuit (See page EGT2−146). 3VZ−FE ENGINE TROUBLESHOOTING − DIAGNOSIS SYSTEMEGT2−11Diagnosis Inspection (Test Mode)Compared to the normal mode, the test mode has high sensingability to detect malfunctions. It can also detect malfunctions in thestarter signal circuit, the IDL contact signal of the throttle positionsensor, air conditioning signal and park/neutral position switch signal.Furthermore, the same diagnostic items which are detected inthe normal mode can also be detected in the test mode.DIAGNOSTIC TROUBLE CODE CHECK1. Initial conditions.(a) Battery voltage 11 V or more.(b ) Throttle valve fully closed (throttle position sensor IDLpoints closed).© Transmission in neutral position.(d) Air conditioning switched off.2. Turn ignition switch off.3. Using SST, connect terminals TE2 and E 1 of DLC2 or data linkconnector 1.SST 09843−180204. Turn ignition switch on.HINT:• To confirm that the test mode is operating, check that themalfunction indicator lamp flashes when the ignition switchis turned to ON.• If the malfunction indicator lamp does not flash, proceed totroubleshooting of the TE2 terminal circuit on pageEGT2−146.5. Start the engine.6. Simulate the conditions of the malfunction described by the customer.7. After the road test, using SST, connect terminals TE 1 andEll of DLC2 or data link connector 1.SST 09843−180208. Read the diagnostic trouble code on malfunction indicatorlamp on the combination meter (See page EGT2−11).9. After completing the check, disconnect terminals TE 1, TE2and El, and turn off the display.HINT:• The test mode will not start if terminals TE2 and E 1 areconnected after the ignition switch is turned on.• When vehicle speed is 5 km/h (3mph) or below, diag.trouble code ”42” (Vehicle speed signal) is output, but thisis not abnormal.• When the engine is not cranked, diag. trouble code”43” (Starter signal) output, but this is not abnormal.• When the automatic transmission shift lever is in the”D”, ”2”, ”L” or ”R” shift position, or when the air conditioningis on or when the accelerator pedal is depressed, code ”51” (Switch condition signal) is output, but this is not abnormal.

Maineah Posted March 26, 2015 Share Posted March 26, 2015 Yep you got it turn up any thing? Got to ask how do you know it's running rich? Quote Link to comment Share on other sites More sharing options...
shibs Posted March 27, 2015 Author Share Posted March 27, 2015 Yep you got it turn up any thing? Got to ask how do you know it's running rich? When I moved it year plus back, my buddy followed me in his vehicle to give me a ride back home, he pointed out that it was running rich and could smell the unburnt gasoline. Nope, won't happen till mid April after I come back from my Walleye trip :-) Quote Link to comment Share on other sites More sharing options...
Maineah Posted March 27, 2015 Share Posted March 27, 2015 If that is the case it should at least have an O2 sensor code my guess he was smelling the cat do it's job. There are things that can make it run rich but the first thing to show up would be a O2 code because it detected a rich mix. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted March 27, 2015 Share Posted March 27, 2015 If history is unknown, never a bad idea to install a new O2 sensor. Especially if the one installed looks like the original. They don't last forever. Quote Link to comment Share on other sites More sharing options...
shibs Posted March 27, 2015 Author Share Posted March 27, 2015 O2 it is, Which one pls, upstream or downstream? are they both the same? Denso? or Bosch? which one should I go with? Quote Link to comment Share on other sites More sharing options...
toyboxII Posted March 27, 2015 Share Posted March 27, 2015 Hi--just did mine--bought a Bosch, but the Toyota mechanic said I should use the Denso, so I went with Denso. Quote Link to comment Share on other sites More sharing options...
Maineah Posted March 27, 2015 Share Posted March 27, 2015 What's the code? Bank one or two? Either will work Bosch or Denso most auto parts place seem to carry Bosch. Quote Link to comment Share on other sites More sharing options...
zero Posted March 28, 2015 Share Posted March 28, 2015 What's the code? Bank one or two? Either will work Bosch or Denso most auto parts place seem to carry Bosch. What is "bank one" or "bank two?" I thought the 3 liter V6 uses a single oxygen sensor, not two. Quote Link to comment Share on other sites More sharing options...
