Hello all, So my truck threw a P0740 code. Where should I start or has this been an issue? 2005 1500 with 4.7 106,000 miles.
Thanks.

The O2 sensors are older than 2 years (I do not know when they were replaced before we bought the vehicle.

Why are there values over 12700% for the 1/1 and 2/1 long term adap?
When I accelerate the value for the 1/1 long term adap goes to 0% and the others remain as they were.

2/1 long term adap 12761.778%
2/1 short term adap between -4% to 5%
1/1 long term adap 12766.26% (*goes to 0% when accelerating)
1/1 short term adao between -4% to 5%
