Question Codes: 94 3.8L

Hey everyone,

Was wondering if someone help me figure out a couple codes that I have.
1. P1401
2. P0161

Is code 1 telling me my EGR valve is bad and if so what years can I get one from?
Is code 2 telling me that I have a bad O2 sensor and if so which one is it?

Thx in advance for the help

Code 1 P1401 is related to the Auxillary Emissions system. I would recommend testing/replacing the DPFM before attempting to replace the EGR system as a whole. The DPFM is that silver box behind the EGR hookup on the upper intake.

Code 2 P0161 is calling for Bank 2 Sensor 2 issues. There are debates on this but you will need to replace the Oxygen sensor on the driver side after the catalytic converters.

Remember, anytime you are dealing with trouble codes you will need to disconnect the battery and allow the proper cycles on the PCM before you will know if the problem is solved. Just cutting off the code will not necessarily prevent it from coming back up.
