Had a CEL on for a bit, and I feel like I need to replace to 02 sensors. Any suggestions where to buy them from, and any ideas if I need to replace both, front, back, ???. There CEL I keep getting is P1114. I'd also seen that it could be the Engine Coolant Temperature Sensor, but my car doesn't have the normal faulty kind. Should I go ahead and try replacing that too? Opinions? Thanks

 

This code? P1114 - Bank 1 - Sensor 2 - internal resistant too high

Replace the postcat o2 sensor. You can get the univeral one from a parts store and then you just splice the wires to the connector. Pretty simple. They universal 4 wire are ~$80 and the ones with the connector are ~$120

 

Alright, thanks a lot. Are there two different types that are used in pre and post cat? Was looking at ECS and they've got 3 different ones listed. OEM Bosch Oxygen Sensor-Front Location, Bosch Oxygen Sensor, and OEM OXS Sensor-In Front Of Catalyst, Primary O2 Sensor. Prices are $70, $150, $130 apiece. Just curious what the differences are on these, and which would be the one I would need. (Would rather plug a connector than splice wires)

 

You want the $150 one with the redish clip. But you can save yourself tons of money if you just strip the wires and twist them together and then electric tape them up. I would solder it, but you dont really have to.

 

Next question - i've read about them being a pain to get out, any tips on removing the sensor?

 

PB Blaster and give it an hour plus to work then you shouldnt have any problems. I use a o2 socket and it makes my life a little easier.
