Title: NGK, Bosch O2 sensors.
Post by: Mutha Jugs n Speed on 16 May 2025, 18:43:03

 Does anyone know of a reliable supplier, of decent quality O2 sensors? As I need a pre cat one, as I stupidly put an ebay one from RTG on, and although they have a five year guarantee, it has only lasted less that a hundred miles and showing a PO150 code. So I'm not going to bother dealing with RTG and the so claimed five year guarantee, I'm just going to get rid, and take the lesson. So any pointers to a good source will be much appreciated :y

Don't rule out loom faults, given the age of the car now, if 2 sensors failed...

 You are right, but the sensor was flagged up on the MOT noting the condition of the connection, but working OK but it was recommended that it be changed, hence the iffy ebay sensor. So I'm thinking, eliminate the cheapo sensor first with a known reliable brand, and if the problem persists then it'll be open the can of worms time. ::)

depends on what"faulty connection actually means " it may be worth refitting this original sensor to see if the fault goes away or swapping both fronts to eliminate wiring issues ?
OR  if the sensor is working fine how about unpinning the connector and fitting the new connector only
