Hey everyone I upgraded my CAI to a K&N and got a jet throttle body spacer along with it.
I also upgraded to a JET MAF sensor as well.
I have been throwing the following codes and am wondering if a small tune is required. Can someone point me in the right direction before I replace my O2 sensor.
Besides the above modifications everything is stock. I am just getting into upgrading. With previous mustangs I would just grab an SCT tuner but need the HP tuner for my truck.
Below are the codes:
0x7E8: P0137 - O2 Circuit Low Voltage (Bank 1, Sensor 2) (SES, Pending, Current, Permanent)
0x7E8: P2270 - O2 Sensor Signal Stuck Lean - Bank 1, Sensor 2 (SES, Pending, Current, Permanent)
0x7E8: P2A01 - O2 Circuit Range/Performance (Bank 1, Sensor 2) (Current)
