Detailed Application Notes

SK2451138 is used in engine air metering systems where the sensor reports incoming air volume to the powertrain control module. When the original sensor becomes contaminated or fails electrically, the engine may run rich or lean, idle poorly, hesitate, or trigger a check engine light. This part cross-references Cardone Reman 74-50040 and Walker Products 245-1138 for the same application.
