Hello, my name is ***** ***** #2 in the in-car fuse box. If the fuse is blown replace it. If there is no battery voltage to the fuse, then check the 40 amp option fuse in the underhood fuse box. Fuse #2 should have constant battery voltage. If the fuses are good, verify the White wire on the harness side of the front A/F ratio sensor has good battery voltage, if not wire is damaged between sensor and fuse. If good then green wire that goes from sensor to ECM needs to be replaced. Let me know how it goes or if you have more questions, thanks.
