need help. My engine goes to max power when starting. Using a techmate pro to check. Came up with the following codes:
1. 1225 fuel fuel quantity sensor signal range high exceeded
2.1515 pedal sensor signal range high exceeded, pedal sensor general sensor plausibility error
3.1201 instrumented injector signal range high exceeded
4.0725 rpm sensor static plausibility

wonder if this is a electrical box or control box problem. Electrical box is out of stock already. Thanks.
