The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Intermittent Diagnostic Trouble Codes P0116 and P0181.

Recommendation/Instructions:

Complete published diagnosis for any trouble codes or symptoms found. If the concern is intermittent, or diagnosis leads to no problem found, there has been a new calibration released to address P0116 and P0181 trouble codes.

The new calibration was released on March 19th 2007, and will address the P0116 and P0181.

When a P0116/P0181 sets, it may induce harsh transmission shifts, and DTCs P0700 and U0100. Disregard DTCs P0700/U0100 if they are set at the same time as P0116 and P0181.

Install the updated calibration for P0116 and P0181 and evaluate the concern.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
