I was previously reading code P1150 on my 2001 model. In attempting to verify the cause of that before replacing the O2 sensor, I cleaned the MAF Sensor and checked the air filter. All was good, CEL was off for a month or more and then it came back on yesterday. A check of the codes showed P1150 plus the other 3 codes referenced in the subject. Thanks to the other threads on these codes, I quickly found the disconnected hose that was the likely cause of the 3 additional codes.

My question is this, is there any way that disconnected hose could have caused P1150 to show again or is it a safe bet that I need a new O2 sensor after all?

Thanks.

Did you disconnect the battery, run the vehicle and then get these same codes again?

We'll have to wait and see. I used the OBD scanner to clear the codes when I read them. The lights did not come back on during the trip home from O'Reilly. I reconnected the hose last night and the car hasn't been driven since. So, I'll let you know. If P1150 re-occurs, I guess I'll know that I need the O2 sensor.

Also let me know if you hook up the scanner if you see both a P1150 and a P1150 p/d (or pending).
