DTC 11

Possible Causes

• •Damaged or disconnected camshaft position sensor or wiring
• •Camshaft position sensor not properly seated
• •Lack of 5V reference voltage / ECM Pin 19 circuit issue
• •Faulty signal circuit
• •No continuity in sensor ground circuit
• •Faulty camshaft position sensor (significant resistance deviation)
• •Difference between the desired CAM position and actual CAM position is greater than 6 CAD
• •Camshaft position sensor lacks a good 5v reference or ground
• •Sensor not properly seated in its position
• •Missing 5V reference voltage
• •Issue with the ground circuit (loss of continuity)
• •Faulty camshaft position sensor

Suggested Actions

1. 1Visually inspect the camshaft position sensor and wiring for obvious damage or disconnections
2. 2Ensure the sensor is properly seated in its position on the right front area of the engine behind the front timing cover
3. 3Connect the 4G Display software with the engine running, navigate to the 'TESTS' page, locate 'Distributor Alignment', and observe CAM position and CAM Position desired values
4. 4Disconnect camshaft position sensor and check for 5V reference on Pin 1 (5V_ext) using a multimeter; trace circuit to ECM Pin 19 if voltage is missing
5. 5Check signal circuit by measuring DC voltage across Pin 2 (CAM +) and Pin 3 (CAM -) while turning the engine over by hand or with a starter to verify voltage fluctuation
6. 6Check for continuity (resistance setting) between Pin 3 (CAM -) on the sensor connector and a good engine ground
7. 7Measure resistance across Pin 2 and Pin 3 of the sensor terminals and compare to manufacturer specifications
8. 8Monitor the CAM position and CAM Position desired value on the 'TESTS' page in the 4G display software under the 'Distributor Alignment' section
9. 9Visually inspect the camshaft position sensor and wiring for any obvious damage or disconnections
10. 10Connect 4G Display software, navigate to the 'TESTS' page, locate 'Distributor Alignment', and observe CAM position and CAM Position desired values
11. 11Disconnect camshaft position sensor and measure DC voltage between Pin 1 (5V_ext) and engine ground to check for 5V reference; trace circuit back to ECM Pin 19 if absent
12. 12Disconnect sensor, measure DC voltage between Pin 2 (CAM +) and Pin 3 (CAM -) while turning the engine over, and check for a fluctuating voltage signal
13. 13Disconnect sensor, set multimeter to Ohms, and check for continuity between Pin 3 (CAM -) and engine ground
14. 14Disconnect sensor, measure resistance across Pin 2 and Pin 3, and compare to specifications to determine if sensor is faulty
