NOTE: You should enter this Pinpoint Test only when you been directed here from Diagnostic Routines.
DESCRIPTION
The Manual Lever Position (MLP) sensor is a ratiometric rotary switch mounted on the transmission range selector linkage. It indicates the position of the shift lever by way of a variable resistance.
REMEMBER:
This Pinpoint Test is intended to diagnose the Transmission Range sensor electrical system only. To prevent the replacement of good components, be aware that the following non-Electronic Engine Controls (EEC) areas may be at fault:
- Electrical
- Battery integrity, ignition switch, starter/relay, harness
- Add-on devices (back-up alarm)
- Transmission
- Shift linkage, Internal components
This Pinpoint Test is intended to diagnose only the following:
- Harness Circuits: SIG RTN, TR, TRR, TRL, TRD and TROD
- Powertrain Control Module (PCM)
