(b) EGR operation possible (Ex. AIT in 3rd speed (5th for MlT), A/C ON, 60 mph (96 km/h), Flat road). DTC 89 - All conditions below are detected 5 secs. or more. (a) No. 1 vehicle speed sensor: 9 km/h (5.6 mph) or more (b) Mirror check of TRAC ECU input signal is abnormal. (c) TRAC ECU input signal does not inform to ECM. (d) TRAC ECU input signal order is abnormal. Have you checked the TRAC DTCs when this happens? The only thing all these codes have in common is the ECM and the wiring harness. Have you tried swapping the ECM? I did have a pin contact issue with my car at the ECM. It generated multiple codes in the ECM and TRAC. I looked at the wiring diagram and there is nothing common to these three pieces in the wiring besides the normal "wires get bundled" issues.

Hey John, ? Totally O.T. question... Were you at TX2K9 back in March? ? This car has had issues with the EGR since before I bought it although they're much better now that it doesn't have completely fubar smoking twins on it anymore.? The EGR parts are still bolted to the head but the vacuum lines are all disconnected and the sensor connector's been resistor'd which helped immensely but didn't solve it. ? I'm wondering if all the crap which included both oil and coolant that was getting past the bad turbo's shaft seal into both the intake and the exhaust has just clogged up the EGR system and coated and upset its' temp sensor.? I've put close to 7k miles on it since the fubar factory turbos were replaced and it doesn't smoke at all anymore so I'm not sure... ? I'm not having any issues with the manu button and?indicator other than once the three codes are tripped including the 89, the manu and trac off buttons don't change the state of their indicator lamps 'till the codes decide to clear or I reset the ecu.

To: "The MKIV.com National Mailing List" Date: Sunday, September 13, 2009, 8:43 AM Thomas, I didn't have the MIL from the EGR (71) until after I put the EGR bypass plate in, and then it only occurred infrequently, in hot weather, and only when cruising between 30 & 50 MPH. I've disabled the rest of the EGR, put the resistor in, replaced the resistor twice, cut the harness and soldered the resistor in, etc. but no joy. The other problems that you're describing, (TRAC Off, Manu, Cruise) I had when I first purchased my car, but they all were sorted when I resoldered all the points in my instrument cluster. My '94 is now owned & driven by my son, but it's still tripping the 71 MIL occasionally, so I'm still keen to find a solution.

Direct from the New Car Features: A340E AUTOMATIC TRANSMISSION  DESCRIPTION Based on the previous model?s A340E automatic transmission, 2 types of A340E automatic transmissions have been perfectly matched to the new 2JZ?GE and 2JZ?GTE engine models. These transmissions offer a highly responsive and smooth driving experience worthy of a sports car. Toyota has never made an E series gearbox for any passenger car.

Some dealers say yes and sell just the two contacts separately from the starter?(with hardware iirc)?for really cheap (like $15-$25ish for both), but some dealers totally?insist that?they're not available separately and will try to make you buy the whole starter which besides being totally unnecessary is obviously a LOT more expensive.? If you can't find them at your local Toyota dealers' parts department and/or they want far too much for them, then just call Jeff Watson?at Champion Toyota or Curt Aigner?at Elmhurst Toyota and they'll get you what you need at a fair price. ? I've purchased and installed the starter contacts?for my?87 MkIII Supra?and several friends' MkIII starters over the past 10 years, I've also replaced them in a couple of friends' higher mileage MkIV's since 2004, and?I just bought a set from Jeff at Champion Toyota?back in March of this year for my 93TT?so I know they can still be had separately?from some Toyota dealers. Also, unless your TT is a conversion, it's the E340i not the A340E?which the MkIII automatic Supras and I think?certain years?of the automatic MkII's also?have.? There are more control/shifting solenoids and more "intelligent" electronics in the MkIV automatic than the A340E has and although they're probably very similar they're certainly not readily interchangeable under normal circumstances and I actually prefer the behavior of the A340E better, stock for stock...? Although a bit more sloppy,?the A340E?was far more predictable and much easier to manipulate with different gas pedal movements, especially when going from cruising to WOT,?and it doesn't have or need the "kick down switch" under the gas pedal like the MkIV's?E340i has, plus I?really liked?the MkII/III's Norm/Pwr mode switch instead of letting the MkIV's?"intelligent" tranny computer try to guess what I really want all the time... But anyway...? :) ? Later dude, ? ?

Can someone tell me what it will take to prep the Supra (98 TT BPU) to pass emissions testing there? I currently live in Indiana and am blessed with zero testing. Another alternative I'm considering is the Washington DC area. Can anyone advise on whether life is hard or easy for a Supra owner in either of these locations?

(We can tell you if they would affect emissions.) Is your check engine light on? (Since the 98 is OBDII, any CEL codes would probably be an automatic fail.) Where in FL? (Does FL even have emissions testing? I don't know, but I would imagine emissions testing varies around the state if it does.)

Just bring title and they look at the car to veryify it is the same as on the paper. I moved to Florida 6 years ago and registration was a snap. Lot's of speed traps though so I would get a good radar/laser detector if you don't have one. One thing you will get are lots of compliments.

Tried the mkiv.com tech article for the odometer cold solder issue but to no avail. I didn't want to do the wire harness hack method so ordered a new odo and it fixed my issue with code 42. Code 71. Dealer cleaned out the EGR piping but it came back about a week later. For my case it turned out to be the EGR modulator. The EGR modulator has a filter and it gets clogged. Do the FSM procedure to verify a clogged EGR modulator. Dealer wouldn't sell the filter separately. A new one if I remember correctly is $60.

I'm not sure but I don't think there was any 'configuration' inspection (n I had a friendly station do it) but just in case I had all the new plumbing powder coated to look stock when I replaced the twins with a single at 225K mi. Never got the chance to 'test' the inspection in VA because I moved to NC while the work was going on. Hope this helps.
