Went to a local Advanced Auto, guy gave me the scan tool (nice guy haha) and i came up with 2 codes both P0161 (the second had a pd superscript ??? ) According to the interweb this is what i came up with


Quote:
What does that mean?

It basically means the PCM detected either an excessive current draw, or an open or short in the circuit powering the oxygen sensor's heater circuit. This is in reference to the Heated Oxygen Sensor (2) located rear of catalytic converter (Bank 2).

Symptoms

There will likely be no obvious symptoms other than MIL illumination.

Causes

A code P0161 may mean that one or more of the following has happened:

HO2S heater power circuit open
HO2S heater ground circuit open
HO2S signal tracking (due to oil or moisture in the connector)
HO2S is damaged or has failed PCM has failed
Possible Solutions

Replace HO2 Sensor
Repair open or short in power circuit
Repair open or short in ground circuit
Repair damaged connector due to tracking


So i erased the code for now, see if it pops back up. drove back (4 miles) and brought up the rpm's, light didnt come back yet.
