What Does P1526 Mean?
The PCM has detected an open circuit in the control circuit for the intake camshaft position actuator on Bank 2. This indicates a complete break in electrical continuity preventing VVT operation on the Bank 2 intake camshaft.
Common Causes
40%
Broken or disconnected wiring between PCM and Bank 2 VVT solenoid
30%
Failed Bank 2 VVT solenoid with internal open circuit
20%
Damaged, corroded, or loose electrical connector at solenoid
8%
PCM internal driver circuit failure for Bank 2
2%
Fuse or relay failure in Bank 2 VVT control circuit
Diagnostic Steps
1
Step 1: Locate Bank 2 VVT solenoid (typically passenger side on transverse, driver side on longitudinal); inspect connector
2
Step 2: Measure resistance of Bank 2 VVT solenoid; infinite resistance confirms internal open circuit
3
Step 3: Check continuity from PCM to VVT solenoid on control and ground circuits; repair any open wires
4
Step 4: Inspect wiring harness routing for potential chafing, pinching, or heat damage
5
Step 5: Verify PCM power supply and ground integrity; test PCM output if all circuits test good
Estimated Repair Cost
$120 - $800
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit in the control circuit for the intake camshaft position actuator on Bank 2. This indicates a complete break in electrical continuity preventing VVT operation on the Bank 2 intake camshaft.
The most common cause of P1526 ("A" Camshaft Position Actuator Control Open Circuit Bank 2) is: Broken or disconnected wiring between PCM and Bank 2 VVT solenoid
Typical repair costs for P1526 range from $120 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is drivable but Bank 2 will operate with fixed cam timing, causing performance loss, rough idle, and reduced fuel economy. Extended driving may damage catalytic converters.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1526 to identify the root cause.
