What Does P2616 Mean?
The PCM has detected an abnormally high voltage in the camshaft position sensor output circuit. This code indicates a communication or circuit fault where the camshaft position signal is being sent to other modules or systems.
Common Causes
35%
Shorted circuit in camshaft position sensor output wiring harness
30%
Faulty PCM internal driver circuit for camshaft position output
20%
Water intrusion or corrosion in output circuit connector
15%
Short to voltage in wiring between PCM and receiving module
Diagnostic Steps
1
Step 1: Inspect camshaft position sensor output circuit wiring and connectors for damage, corrosion, or shorts to voltage
2
Step 2: Using a digital multimeter, measure voltage on the output circuit with key on, engine off (should be specified voltage, typically 0-5V)
3
Step 3: Disconnect receiving module and check for short to voltage in the harness
4
Step 4: Check for PCM software updates or TSBs related to this fault
5
Step 5: If all wiring tests pass, suspect faulty PCM output driver circuit
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
The PCM has detected an abnormally high voltage in the camshaft position sensor output circuit. This code indicates a communication or circuit fault where the camshaft position signal is being sent to other modules or systems.
The most common cause of P2616 (Camshaft Position Signal Output Circuit High) is: Shorted circuit in camshaft position sensor output wiring harness
Typical repair costs for P2616 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience rough running, stalling, or fail to start. May cause drivability issues but typically not immediately dangerous.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2616 to identify the root cause.
