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.

 

i set the new TPS to .45 a few days ago without conzult but used a multimeter to set it to .45 volts and today conzult is coming up as .46 in engine mode section but on the A/T mode it says .50 is this normal???

 

All cylinders came up green. and no error codes in the ECU.

 

So what do you guys think?

what happens if you erase the codes ?

those may be old codes

 

if you are certain the tps is working correctly it may indicate faulty wiring (do you have a HKS ALC?) or there's something wrong with the ATCU itself (swap it with another one)

I havent tried eraseing the codes as i wasnt sure it would remove the error from the ECU's memory. I am new to Conzult so need to practice to learn about this stuff:). My auto has had shifting problems for the past 8 months. I have tried heasp of times to activate the Auto Diagnostics problem but it has never started for me and i brought Conzult as a way to do the diagnostics.

 

What is HKS ALC?? I agree there must be a short in the harness somewhere but i dont know where to look yet. Probably should get my mechanic to look at it.

Ok so i decided to try and erase the codes and then check the result of the AT diag. and now im getting alot of extra errors and or less errors.

 

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??

> Would this inconsistency mean the AT control unit itself is damaged??

 

this could be the case.

 

or...as it indicates: the battery voltage may be too low.

So, erase errors and check again with the engine running (battery voltage should be ok then)

 

if the same errors keep coming back, it'd swap the ATCU with another one to see if it's the control unit causing the errors.
