Ok i finally hooked up my conZult program to my car to test the A/T for error codes and this is what came up Now i have just replaced my TPS unit with a brand new one so im guessing their might be a short somewhere in the harness. All cylinders came up green. and no error codes in the ECU. So what do you guys think. I am going to check the service manual about the speed sensor now.
did you adjust the TPS to .45mv? also try reconnecting the old one and see if the error goes away. Speed sensor tells the transmission how fast your cars going.
Yes i set the new TPS to .45 and conzult is coming up as .46 in engine mode but on the A/T mode it says .50 is this normal??? I also checked the idle adjusted and when i selected this function when the car was at operating temps my revs dropped from 900 down to 750-800 and then back up to 900 when i close it down. Is this normal?? I didnt adjust it yet guess i gotta do it manually with the AAC adjuster screw yeh??
Yep the revs thing is normal when selecting that test, when you select that function and the revs drop the ecu is no longer in control and this is when you set your base idle, then once its set turn that function back off and the revs will jump around 50rpm or so which is the ECU taking back over, yep adjust the revs with the AAC screw. I dont know about the .50mv. It says TPS signal which makes me think that the TPS is working but the transmission isnt getting any signal.
Cheers thanx for the help. As ivce never used this program i need to learn how to use it. I will adjust the base idle later today. I agree with you on the TPS signal. This is what worries me as where do i go to look for the shorted wire in the harness. Im thinking of getting my mechanic to fix it for me as he knows what he is doing??
I could check your car for you. If your interested pm me and we can organise a time and date. The BlaZt cable only cost me $110 and you can get the free version of Conzult from the net.
Once you have set the base idle and exited the program you need to unplug the TPS to reset the throttle closed position within the ECU. Unplug the big grey plug and count to 10, then plug it back in.
No probs. I did the self learn when we set up the new TPS. Did exactly what you said. Ill do the same once ive set the base idle as well.
OK no things are getting complicated and confussing. I posted the results up on the uk forums to see what they thought and they suggested i erase the codes to check they arnt old stored codes. So i decided to try and see the result of this and im now getting more errors appearing. First time i checked all was indicated was the TPS signal no VHC sensor lised. So i erased the code and checked the diagnostics again. This time it stated no errors. I thought this might be a case of the program still running and keeping the error code deleted. So i turned off conzult and tested again. Here is what i came up with I deleted the codes just to double check and again no error codes and after a few attempts of closing down conzult turning the car on and off and starting the AT diag. i got this next set of errors So no im unsure which error is right or wrong now. Would this inconsistency mean the AT control unit itself is damaged??
