Tps problem

Post by broor » Sun Jan 06, 2019 3:06 pm

Hello All

A small introduction :) i'm Broor from the Netherlands and owning a 2gn 2.0 Neon with a custom turbo build on.

I bought this project from another guy who had trouble with the emission limits here on our yearly test what all cars must have.

When i bought the car from him he was already started to part it out a bit so he cutted the E-Manage blue harness to pieces. I managd to solder this back and am able to start the car no problems there.

But my idle rev was toggeling from 1000 to 3000 rpm and the error P0122 came up.

Then i started to search and measuring but here i come up to a wall.

My resistance from the tps sensor is: 730 ohm closed and 1750 ohm fully opend tb

On ignition
In voltage's it is: 0.7v closed and 3.6v fully opend.

I checked all the wires etc. And no bad wires there so far i looked from tb to the pcm.

Anyone a idea in what direction i should search?

Also i checked the PCM 5v output (pin 61) this puts out 8v idk if this is common or already a red flag

Greetings Broor
