Circuit/System Description
Each camshaft is equipped with a camshaft position sensor that
the engine control module (ECM) monitors. The camshaft
position sensor is a hall effect switch that works in conjunction
with a 4X reluctor wheel. The reluctor wheels are mounted to the
camshaft position actuators that are mounted to the end of the
camshafts. The ECM uses the camshaft position sensor signals in
order to determine the position of the camshafts. The ECM supplies
5 V to the camshaft position sensors on the 5 V reference
circuits and supplies a ground on the low reference circuits. The
camshaft position sensors provide a signal to the ECM on the signal
circuits.
Conditions for Running the DTC
• |
DTC P0101 00, P0102 00, P0103 00,
P0335 00, P0336 00, P0641 00, or P0651 00 are
not set. |
• |
The engine is cranking or running. |
• |
The mass air flow (MAF) is greater than
3 g/s. |
• |
The DTCs run continuously when the above
conditions are met. |
Conditions for Setting the DTC
• |
The ECM detects that the starter is commanded ON,
and the engine has been cranking for greater than 2 s, without
a camshaft position sensor pulse. |
• |
The ECM detects that the engine has started, but
did not receive a camshaft position sensor pulse during the first
engine revolution. |
• |
The ECM detects that the engine is running, but
does not receive a camshaft position sensor pulse for 80 out of
100 engine cycles. |
Action Taken When the DTC Sets
• |
DTCs P0340 00, and P0365 00 are
Type B DTCs. |
• |
The camshaft position actuator is commanded to the
park position. |
Conditions for Clearing the DTC
DTCs P0340 00, and P0365 00 are Type B
DTCs.
Diagnostic Aids
With a DTC set, the engine may crank for an extended period of
time during start-up.

Circuit/System Verification
- Ignition ON, observe the DTC information with a scan
tool. DTC P0641 00 should not be set.
- Engine idling, observe the scan tool Intake Camshaft
Position Active Counter and Exhaust Camshaft Position Active
Counter parameters. Both parameters should be incrementing.
- Engine idling, observe the DTC information with a scan
tool. DTC P0340 00 or P0365 00 should not set.
- Operate the vehicle within the conditions for running
the DTC to verify the DTC does not reset. You may also operate the
vehicle within the conditions that you observed from the freeze
frame/failure records data.
Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the
B23F Camshaft Position Sensor - Intake or B23E Camshaft
Position Sensor - Exhaust.
- Test for less than 5 Ω between the low reference
circuit terminal 2 and ground.
⇒ |
If greater than the specified range, test the low
reference circuit for an open/high resistance. If the circuit tests
normal, replace the K20 Engine Control Module. |
- Ignition ON, test for 4.8-5.2 V between the
5 V reference circuit terminal 1 and ground.
⇒ |
If less than the specified range, test the
5 V 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
5 V reference circuit for a short to voltage. If the circuit
tests normal, replace the K20 Engine Control Module. |
- Ignition On, test for 4.8-5.2 V between the
signal circuit terminal 3 and ground.
⇒ |
If less than the specified range, test the signal
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
signal circuit for a short to voltage or an open/high resistance.
If the circuit tests normal, replace the K20 Engine Control
Module. |
- If all circuits test normal, test or replace the
B23F Camshaft Position Sensor - Intake or B23E Camshaft
Position Sensor - Exhaust.
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
