Thread: 1995 Nissan 200sx Se-R O2 Sensor Question

My car check engine light is on and i went to a shop and they told me i need a 02 sensor heater PO 135.

I know my car has two O2 sensors. which one is it?

Help!!

on most cars the front o2 (in the exh manifold) is the one that fails first.

P0135.

Thanks

That OBD-II Trouble code site was very helpful.

NP, good luck and remember you can save a few bucks by not getting a new O2 from Nissan, but getting a universal (that matches our cars via Bosch's site), and just crimp it on.

If you have a Stainless Steel header on your car a 4-wire Bosch O2 Sensor is a must!
