To: All Jeep/Eagle Dealers

Subject: Safety Recall # 301T - Throttle Position Sensor

(Comanche) Vehicles Equipped With 4.0L MPI Engine and Automatic Transmission, Vehicles Built From May 1, 1989 Through June 6, 1990


The listed model vehicles may experience an intermittent high idle condition immediately following engine start. This is caused by a false signal from the throttle position sensor (TPS) which indicates that the throttle is not closed. The condition results from poor internal wire-to-connector crimping in the TPS.

To correct the condition, a new TPS must be installed and adjusted.
