Afternoon all,

 

Have searched this code and I can see it relates to post cat lambda sensor.

 

What is the best way of troubleshooting this?  I have cleared the error with op-com for now to see if it returns.  Is it easiest to swap the sensor out in the first instance?

 

Car is Stg 2 SC, pre cat removed and full Miltek

 

Cheers

Probably a broken wire = new sensor. Does anyone know if there is a cheater available, seem to remember there was talk of one.

on the lambda plug , check the voltage on the #RED-WHITE wire

I've still got a load of PCB's for the cheater I made, and a few resistors riveted to Ali heat sinks etc.

I dont have the time to do much with it though

Had this on my old MR2, made no difference to the running of the car, I bought a new sensor but you can wire in a cheater I think.

[font="arial, helvetica, sans-serif;"][color=rgb(0,0,0);]I have actually the same error-problem but it was only after changing to a new cloned ECU with obd-tuner.[/color][/font]

Think the error comes in the warming up phase. Also SC stage 2, no pre cat and 200 cpi sportscat.

Do you have also the obd-tuner Software?

This is interesting as I recently switched to a new ECU with OBD Tuner when I had the SC conversion done.  The error appeared around 500 miles after moving to the dutch software so I cant say for sure if it is a result of that or a faulty sensor.  My setup is identical to yours though which ties in.

 

Have you contacted Peter yet regarding this?

[KAMIKAZESPEEDSTER]

Yes. And I send him a log file. The sensor is o.K. and I should delete the error again. Than I will create a new log direct after cold start.  

So in the moment no idea.

Before spending a load on a new lambda try a bottle of Wynns lambda and cat cleaner. Did the trick for me

Ok great , please keep this thread updated with your findings if you can please.

 

I am going to try and test the sensor at the weekend.

[KAMIKAZESPEEDSTER]

Today and yesterday I am driving over 1h through the area and… no pid-error. Also obd-tuner says now that the lambda-test is O.K. 

So I think the problem was the second lambda.  Before I changed the lamda I start the engine to jack up the speedy and I don’t check the errors again before I test the new one.

THanks for the update Kamikaze, I will get the sensor checked.
