What Does P1535 Mean?
The PCM has detected a short to ground condition in the intake camshaft control circuit on Bank 2. This prevents proper control of the intake camshaft variable valve timing system.
Common Causes
40%
Wiring harness shorted to ground or chafed through insulation
30%
Failed intake camshaft actuator solenoid with internal short
15%
Damaged connector pins causing short to ground
10%
Water or oil contamination in connector
5%
Failed PCM with internal short
Diagnostic Steps
1
Step 1: Disconnect Bank 2 intake camshaft actuator connector and clear codes; if code returns, short is in wiring harness
2
Step 2: With actuator disconnected, measure resistance between control circuit wire and ground; should be infinite resistance
3
Step 3: Thoroughly inspect wiring harness for chafing, pinching, or damage along entire route from PCM to actuator
4
Step 4: Measure resistance of disconnected actuator solenoid to ground and between terminals to verify no internal short
5
Step 5: Check for oil or coolant contamination in connector or wiring harness that may cause intermittent shorts
Estimated Repair Cost
$120 - $650
Parts + labor, varies by vehicle and location
The PCM has detected a short to ground condition in the intake camshaft control circuit on Bank 2. This prevents proper control of the intake camshaft variable valve timing system.
The most common cause of P1535 (Intake Camshaft Contr.Circ.,Bank2 Short to Ground) is: Wiring harness shorted to ground or chafed through insulation
Typical repair costs for P1535 range from $120 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but may experience reduced performance, rough idle, and poor fuel economy. Continued operation with short may damage PCM.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1535 to identify the root cause.
