#31 of 33 02 Sentra Spec V QD25 O2 Sensor Selection? by huck76 Jul 14, 2009 (5:58 am)
How do I tell wich model of O2 Sensors that I have? There are DTC PO132 HO2S1, DTC PO133 HO2S1, DTC PO134 HO2S1, and DTC PO138 HO2S1. Can I tell with the Car Serial or VIN if I cant take one of the sensors off? Thanks in advance for help.

The black wire is for the signal and grey is ground. Refer to a vehicle wiring diagram to be sure the wires are connected correctly. After the wires are connected correctly you will be able to reset the check engine light Replies to this message: corkscrew (Jul 14, 2009 3:09 pm)
