Clutch Pedal Position Sensor / Switch: Testing and Inspection
DIAGNOSIS AND TESTING-CLUTCH INTERLOCK/UPSTOP SWITCH
LHD and DIESEL LHD & RHD
NOTE: 2.4L-equipped models (including Turbo) do not use the clutch pedal upstop switch/feature. These vehicles will only utilize the starter
inhibit (interlock) feature.
The clutch interlock/upstop switch (1) is an assembly consisting of two switches: an engine starter inhibit switch (interlock) (2) and a clutch pedal upstop
switch (1). The switch assembly is located in the clutch/brake pedal bracket assembly, each switch being fastened by four plastic wing tabs. The
connector (3) is secured to the pedal/bracket assembly by a plastic retainer.
RHD-2.4L
The RHD clutch interlock/upstop switch (1) consists of a single, multi-function switch that is activated by the hydraulic clutch master cylinder push rod.

Mechanical Test
1. With the park brake set and the transaxle IN NEUTRAL, turn the ignition key to the start position. The engine starter should not crank with the
clutch pedal at rest (not depressed). If the starter cranks, proceed to the electrical test to determine whether the switch is defective or the circuit is
shorted. If the vehicle does not crank, proceed to the next step.
2. With the park brake set and the transaxle IN NEUTRAL, fully depress the clutch pedal and turn the ignition key to the start position. The engine
starter should crank. If the starter does not crank, visually inspect the clutch pedal for obstructions (floor mat, etc.) and for proper installation of
the master cylinder push rod/bushing on the pedal pin. Also make sure the clutch pedal lever contacts and fully closes the switch for LHD and
Diesel RHD applications.
