Service bulletin 01-027-13-2836a

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some vehicles may experience MIL illumination with DTC P219A:00 and/or P219B:00 stored in PCM memory. The DTCs may be caused by abnormal electrical noise within the engine harness of certain vehicles. To elimi-nate this concern, separate the A/F sensor signal lines from the emission harness by installing the short cord service part detailed in this bulletin.
