Diagnostic Aids

The following conditions may cause this DTC to set:

Incorrect harness routing near secondary ignition components
Ignition coil arcing to wiring harness or IC module-Inspect the ignition coils for cracks, for carbon tracking, or for other signs of damage.
Camshaft reluctor wheel damage.
The sensor coming in contact with the reluctor wheel.
Foreign material passing between the sensor and the reluctor wheel.
Excessive camshaft end-play.

If the condition is intermittent, refer to Intermittent Conditions .

DTC P0341

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Component Views or Powertrain Control Module (PCM) Connector End Views
1	Did you perform the Diagnostic System Check-Engine Controls?	-	Go to Step 2	Go to Diagnostic System Check - Engine Controls
2	Start the engine. Observe the CMP sensor signal present parameter with a scan tool. Does the scan tool indicate the CMP sensor signal is present?	-	Go to Step 3	Go to Step 4
3	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 4	Go to Diagnostic Aids
4	Turn OFF the ignition. Remove the power steering pump. Refer to Power Steering Pump Replacement (3.1L)Power Steering Pump Replacement (3.8L) in Power Steering System. Disconnect the CMP sensor connector. Turn ON the ignition, with the engine OFF. Probe the 12-volt reference circuit of the CMP sensor harness connector with a test lamp that is connected to a good ground. Refer to Probing Electrical Connectors in Wiring Systems. Does the test lamp illuminate?	-	Go to Step 5	Go to Step 8
5	Turn OFF the ignition. Jumper the CMP circuits from the CMP sensor to the CMP sensor harness connector. Refer to Using Connector Test Adapters in Wiring Systems. Turn ON the ignition, with the engine OFF. Measure the Voltage Drop from the low reference circuit of the CMP sensor to a good ground with a DMM. Refer to Circuit Testing in Wiring Systems. Is the voltage more than the specified value?	0.2 V	Go to Step 9	Go to Step 6
6	Remove the jumpers from the CMP circuits. Start the engine. Observe the CMP sensor signal on the scan tool. Momentarily and repeatedly probe the signal circuit of the CMP sensor with a test lamp that is connected to battery voltage. Does the CMP sensor signal change when the test lamp contacts the signal circuit?	-	Go to Step 12	Go to Step 7
7	Turn ON the ignition, with the engine OFF. Probe the signal circuit of the CMP sensor harness connector with a test lamp connected to a good ground. Refer to Probing Electrical Connectors in Wiring Systems. Does the test lamp illuminate?	-	Go to Step 11	Go to Step 10
8	Test the CMP 12-volt reference circuit between the CMP sensor and the PCM for an open or for high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 18	Go to Step 13
9	Test the CMP Low reference circuit between the CMP sensor and the PCM for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 18	Go to Step 13
10	IMPORTANT: Disconnecting the PCM may remove the short from the circuit. Test the CMP signal circuit between the CMP sensor and the PCM for a open or for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.Did you find and correct the condition?	-	Go to Step 18	Go to Step 13
11	IMPORTANT: Disconnecting the PCM may remove the short from the circuit. Test the CMP signal circuit between the CMP sensor and the PCM for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.Did you find and correct the condition?	-	Go to Step 18	Go to Step 13
12	Test for an intermittent and for poor connections at the CMP harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 18	Go to Step 14
13	Test for an intermittent and for poor connections at the PCM harness connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 18	Go to Step 17
14	Remove the CMP sensor. Refer to Camshaft Position (CMP) Sensor Replacement . Visually inspect the CMP sensor for the following conditions: Physical damage Loose or improper installation Did you find and correct the condition?	-	Go to Step 18	Go to Step 15
15	Visually inspect the CMP sensor reluctor wheel for damage. If the CMP reluctor wheel is damaged, refer to Camshaft and Bearings Cleaning and Inspection in Engine Mechanical. Did you find and correct the condition?	-	Go to Step 18	Go to Step 16
16	Replace CMP sensor. Refer to Camshaft Position (CMP) Sensor Replacement . Did you complete the replacement?	-	Go to Step 18	-
17	Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement . Did you complete the replacement?	-	Go to Step 18	-
18	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 2	Go to Step 19
19	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List	System OK
