The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
On rare occasions, a SES light may be experienced due to a P0442 and/or a P0455 DTC.
Recommendation/Instructions:
If the SI diagnostics do not isolate a cause for this concern, inspect the accordion style EVAP line shown below for a small hole. If a hole is present, it will be necessary to replace the complete fuel tank since this line is not serviced separately. The new fuel tank will come with a new line.
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.
