NOTE: You should enter this Pinpoint Test only when you been directed here from Quick Test.
REMEMBER
This Pinpoint Test is not intended to diagnose components interior to the transmission. To prevent replacement of good components, be aware that the following non-EEC areas may be at fault:
- Electrical
- Generator, battery integrity.
- 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, MLP, TRR, TRL, TRD and TROD
- Powertrain Control Module (PCM) (12A650) or (12B565 on 7.0L Diesel)
DESCRIPTION
The Manual Lever Position (MLP) sensor is a rotary switch mounted on the transmission shift linkage. It indicates the position of the shift lever by way of a variable resistor.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
