Title: o2 sensor question
Post by: dexetr30 on January 22, 2009, 10:32:08 AM

Check engine light is on. Throwing codes:

P0037 HO2S Heater Control Circuit Low (Bank 1 Sensor 2)

P0138 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)

Just checking... bank 1 sensor 2 is the o2 sensor after the cat. Is this correct?

Yes it is, check to see of there 12 volts available for the o2 sensor heater circuit once that is good see what happens might just solve the problem. Either way it does not hyrt to run it like this. The second sensors sole job is to measure catalitic convertor efficiency

Thanks. It started throwing a code soon after I replaced the trans. I think I may have accidentally messed up the plug on the o2 wire harness at some point.
