code P0123- WTF!?

[changedman]

I scanned my ECU, as expected, I still have code P0401: EGR flow insufficient. However, I was suprised to see another one- P0123- Throttle Position Sensor Circuit High Voltage. WTF?!

I had my MPI installed for one day, then i took it back out and went to stock because i didn't have my turbo kit yet and my car was very unreliable.

WTF is this code all about?

Did you make sure all coneections are back to stock and secure? When you took out the MPI, was the battery unhooked? If not, you may have gotten a surge when you disconnected the TPS. It's pin 89 and you should of had the brown wire to it.

i prolly didnt have have the battery off. hmm.

if i had a surge, i just cleared that code, and can expect it not to come back?

If the battery was not disconnected and you just got a surge, then yes if you reset it, it won't come back. But if it damaged the TPS, which I don't think would of happened, then you will get it again and will need to troubleshoot it more. Let us know, and never work on the ECU with the battery still hooked up.

and for the record- im SICK OF GETTING the p0104 code- its takes 15 miles to be pending. ARGH!

 

[Matthew]

just for the record what in the **** is the 0104 code? are you referring to the eGR insufficience flow code?
