P0131 and P0132 at same time ('56 Zetec S)

Recommended Posts

Hi - Zetec S '56 plate here

 

Engine management light came on today on drive home (I don't know if it could be a contributing factor whatsoever, but it was slow rush hour drive in minus 3 temperatures)

Hooked car up to a code reader and it's chucking out P0131 (O2 Sensor Circuit Low Voltage Bank 1 Sensor 1) and P0132 (O2 Sensor Circuit High Voltage Bank 1 Sensor 1) simultaneously which has me puzzled. Normally I would have assumed it's the sensor itself playing up - but I got the Lambda sensor changed no more than 2 months ago when it threw out a P0030 code and failed the MOT emissions test - both of which were remedied once it was done.

I hear that they can fail again, but the fact different codes have come up has surprised me

Anyone have advice for what to pursue or similar issues since fixed?

 

Any help greatly appreciated

I don’t know . But I would clear codes and see if they come back. Was it in limp mode?
