Help with SES Codes!!!

**mikeaford** · 09-14-2007, 07:38 AM

I have an 01 T/A mods are cold air intake, small cam, 3 angle grind on the stock heads, long tube headers, magnaflow cats and magnaflow cat back. It has been tuned and I am receiving the following codes pulled by autozone = PO140, PO140 PD, PO160, PO160 PD. I don't have the rear 02 sensors anymore and I believe the tuner forgot to delete them from the system. I just had the front 02 sensors check yesterday and they appeared to be doing exactly what they should according to the shops scanner. But the tuner was not in so I couldn't ensure that they had been deleted. Any ideas on what these codes mean? I do have o2 sensors for the front pre cat but not after. I suppose I could have bungs welded into my y pipe and put them back in but I'd rather just say see ya to the sensors.

According to my Database those signals are set from either the PCM or a Heated Oxygen sensor failure, if you have deleted the sensors, I would guess thats it. You can have the tuner delete those codes or run a Sim.
Not much info, but I hope it helps.

those are for the rear sensors. the tuner forgot to turn the codes off.

Good deal I should be able to get up there next week to have him double check that code. I greatly appreciate the insight and love what my car is transforming into minus the ses lights...
