Official summary
Special Coverage. Certain vehicles, equipped with a 2.8L diesel engine (RPO LWN), could have a condition that may intermittently cause the throttle body motor to fail to complete the throttle position learn cycle within the allowed time. If this condition were to occur, the Malfunction Indicator Lamp (Check Engine Light) would illuminate, and a diagnostic trouble code would set. The engine may also be placed in a reduced power mode. Dealers are to replace the throttle body as necessary. The repairs will be made at no charge to the customer.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
