Forum rules


When you put a new thread up in the Workshop please put your car's year of registration (not plate or model year) in the post subject/thread title, along with just a brief indicator of the problem.

Registration Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot.

For Tech II issues or help requests please state the following in your title ''Tech 2 help required - state issue and your location ''.

Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.

Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum, note compliant threads will be moved back when the mod/admin team next visit the Pit Lane. if your thread has been sat in the Pit Lane for 24hrs+ after editing, pm Tech II to request release)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

I'M new to this stuff so

I have the error code P1902 on the obe II thing

error reads, P1902 then underneath it it says.

manufacturer control ?

car still runs as sweet as a nut and still gos like poo of a shinny shuvel but the EM light is on, reset it one and stayed off the complete run in the car but came back on after stopping and then starting again,

i cleaned the egr valve well over 3 months ago and it was spotless so im lost as to what this one means.

thank you in advance

bob.

There are two sub-codes for P1902, both related to wiring or electrical faults

You might be able to check for shorting across the terminals, or open circuit. Or it could be corrosion of the connector pins.

Wires to the sensor are shown as Brown/White & Blue/Green. They connect directly to the Engine Management unit which is hidden in the front of the right hand wheel arch under the wheel arch liner under the headlight. The pins here can corrode.

The intermediate connector is under the coolant reservoir.
