P0365

DTC P0365

Circuit Description

The exhaust camshaft position (CMP) sensor produces a 5X plus a sync signal for each revolution of the exhaust camshaft. These signals are for control of sequential fuel injection and for exhaust camshaft phaser control. The CMP is connected directly to the powertrain control module (PCM) and consists of the following circuits:

* A 12-volt reference circuit
* A low reference circuit
* A CMP sensor signal circuit

If the PCM does not receive 5 CAM pulses within a certain amount of time, DTC P0365 will set.

DTC Descriptor

This Diagnostic procedure supports the following DTC:

DTC P0365 Exhaust Camshaft Position (CMP) Sensor Circuit

Conditions for Running the DTC

* The engine is running.
* DTC P0365 runs continuously when the engine is running.

Conditions for Setting the DTC

The PCM does not receive 5 CAM pulses within 3 seconds.

Action Taken When the DTC Sets

* The malfunction indicator lamp (MIL) will illuminate after two consecutive ignition cycles in which the diagnostic runs with the fault active.
* The PCM records the operating conditions at the time when the diagnostic fails. This information stores in the Freeze Frame and Failure Records buffers.
* A history DTC stores.

Conditions for Clearing the MIL/DTC

* The MIL will turn OFF after three consecutive ignition cycles in which the diagnostic runs without a fault.
* A history DTC will clear after 40 consecutive warm-up cycles without a fault.
* Clear the DTCs with a scan tool.

Diagnostic Aids

* The following conditions may cause this DTC to set:

- Damage to the camshaft reluctor wheel
- Damage to the CMP sensor
- The sensor coming in contact with the reluctor wheel
- Foreign material passing between the sensor and the reluctor wheel

* If the condition is intermittent, Refer to Intermittent Conditions. Intermittent Conditions

Test Description

Step 1 - Step 8:

Step 9 - Step 17:

The number below refers to the step number on the diagnostic table.
7. This step tests the CMP sensor signal circuit. If the CMP Active Counter counts when the circuit is touched, it is OK.
