Yesterday whilst doing about 90 on the motorway my CEL Illuminated. I slowed down for a few minutes and stayed off boost and it went off. I checked the code when I got home and found 32 (O2 sensor)
The thing is I only changed this in october and fitted a Bosch sensor so I'll be Pissed if its gone again! Any Ideas why???? Its an MY97 WRX.
I should add that I may of nudged 120 a couple of times (Top gear was starting at 8)

Thanks in advance

 

Have you checked that your MAF sensor is functioning as it should? Under certain circumstances a failing air flow meter can cause the ECU to think the lambda sensor is reading odd...

 

That is interesting. I posted a thread about checking My MAF last month but determined in the end it was ok. Read a max of 4v's. The reason I checked it was the car did not stall when I unplugged the MAF.

 

Any one else got any views on this I could do with a few points of view??

 

just because you can read a voltage on the maf doesnt suggest its ok

if your car didnt stall while unplugging the maf then something is wrong with it

get it replaced

 

I'm getting Mixed reactions again. Checked maf again at Dinner time. Results were:
Around 0.2v Ign On
0.9v @ Idle
4.1v @ WOT in 4th gear (around 7k rpm)

No CEL light
Anymore for anymore???
