- Scanned vehicle for codes. Vehicle had the same codes as customer had stated. Checked wiring diagram and found one common fuse that feeds both upstream and downstream O2 sensors. Removed IPDM to gain access to fuses and found #38 was blown. Replaced fuse and checked O2 values. All values are appropriate. Checked for common chafe points on harnesses and all looked good. Suspect a bad A/F or O2 sensor. Customer will return for further diagnosis if light persists. He suspects it had to do with a deep puddle he had to go through recently.
