Complaint Customer states the CEL is on in the instrument cluster. May also report rough running. Cause Under investigation Remedy Follow the instructions "232 Diagnosis and Repair_CEL for P152C00" in the attachments. If after the "short road test" (step 5 on page 4) the CEL remains off, release the vehicle. If the CEL returns, open a PTSS case and include all the attachments requested in the instructions. If the vehicle has returned after previously having this LI applied to it, do not perform the LI a second time and instead immediately open a PTSS case with a IQT and ME CUL.
