Circuit/System Description
The clutch pedal position (CPP) sensor is a three wire sensor,
connected to a 5V reference circuit, a low reference circuit, and a
signal circuit. The engine control module (ECM) supplies 5 V to the
CPP sensor, and also provides a sensor ground path on the low
reference circuit. The CPP sensor sends a voltage signal to the ECM
on the signal circuit. The voltage on the signal circuit will vary
from a voltage less than or equal to 5 V when the clutch pedal is
released, to a voltage less than or equal to 1.5 V when the clutch
pedal is applied.

Circuit/System Verification
2. |
Ignition ON, observe the scan
tool CPP Sensor percent parameter. The percentage should vary from
0% when the clutch pedal is released, to 100% when the clutch pedal
is in the apply position. |
4. |
Operate the vehicle within the
conditions for running the DTC to verify the DTC does not
reset. |
Circuit/System Testing
1. |
Ignition OFF, disconnect the
harness connector of the B25B Clutch Pedal Position Sensor.
|
2. |
Ignition OFF, test for less
than 1 Ω between the low reference circuit terminal A and
ground. |
⇒ |
If greater than the specified value, test the low
reference circuit for an open/high resistance. If the circuit tests
normal, replace the K20 Engine Control Module. |
3. |
Ignition ON, test for 4.8-5.2
V between the 5V reference circuit terminal C and ground.
|
⇒ |
If less than the specified range, test the 5V
reference circuit for a short to ground or an open/high resistance.
If the circuit tests normal, replace the K20 Engine Control
Module. |
⇒ |
If greater than the specified range, test the 5V
reference circuit for a short to voltage. If the circuit tests
normal, replace the K20 Engine Control Module. |
4. |
Ignition ON, observe the scan
tool CPP sensor voltage parameter for less than 0.1 V. |
⇒ |
If greater than the specified value, test the
signal circuit for a short to voltage. If the circuit test normal,
replace the K20 Engine Control Module. |
5. |
Install a 3 A fused jumper
wire between the signal circuit terminal B and the 5V reference
circuit terminal C. Verify that the scan tool CPP sensor parameter
is between 4.8-5.2 V. |
⇒ |
If not within the specified range, test the signal
circuit for or a short to ground or an open/high resistance. If the
circuit tests normal, replace the K20 Engine Control Module. |
6. |
If all circuits test normal,
test or replace the B25B Clutch Pedal Position Sensor. |
Component Testing
Static Test
1. |
Ignition OFF, disconnect the
harness connector of the B25B Clutch Pedal Position Sensor.
|
2. |
Measure the resistance between
the signal terminal B and the low reference terminal A of the B25B
Clutch Pedal Position Sensor. Depress the clutch pedal through the
entire range. The resistance should vary from high to low and vice
versa without any spikes or dropouts. |
⇒ |
If the resistance is erratic with spikes or
dropouts, replace the B25B Clutch Pedal Position Sensor. |
