Open Loop Fault On Diagnostic

[Stasi]

Good Morning,

 

just wondered if anyone could confirm my diagnosis of a fault on 2.0 HPi C5; Intermittent P0132 dtc (O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor1)) and open loop system fault....

 

my feeling is precat o2 (lambda) sensor; could anyone give me the benefit of their expertise on this? Fuel consumption is up a bit but apart from that running ok.

 

If the consensus is that the precat sensor is to blame, is this the expensive 5-wire one? or the not quite so expensive 4 wire unit?

 

Regards

its the first o2 sensor from the exhaust manifold and could be wiring short to earth or the sensor has had it

I wonder.... the mil came on the other day as i navigated a really badly corrugated road surface; hopefully wiring shorting to earth.... otherwise its over a ton for the 5-wire sensor, if that is the one that I would need and all indications are that is the case, have you any experience of the universal type? they are 'only' 45 quid......

 

thanks for your help

considering you are trying to repair a fault, and are possibly unsure as to whether the part you are about to replace is the culprit.....i would use a genuine part.

 

Why?......because when it hasnt cured the fault you wont be wondering if the 'pattern part' is correct for the vehicle.
