P0013 "B" Camshaft Position Actuator Circuit (Bank 1)
Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modePossible
The engine control module drives the oil control valve (a pulse-width modulated solenoid) of the variable valve timing on the exhaust camshaft on bank 1. It checks the electrical state of this output and sets the code when the circuit is open, or when the measured state does not match the command, for example because of a short. Camshaft adjustment is then disabled and the phaser stays in its locked rest position: the engine keeps running, but with less torque and higher consumption. Bank 1 is the cylinder bank that contains cylinder 1.
Likely causes
Solenoid coil of the oil control valve open or shorted
Connector corroded, loose or soaked with engine oil wicking through the valve
Wiring harness chafed through or broken
Supply voltage missing, e.g. blown fuse
Output driver in the engine control module faulty
Symptoms
- Check engine light on
- Less pulling power at low and medium engine speed
- Rough idle in some engines
- Slightly higher fuel consumption
Repair estimate
DifficultyMediumDIY possible
Parts and labour€50–300
Time0.3–2 h
Typical range across vehicles; the real cost depends on what the testing finds.
What to check first
- Inspect connector and wiring
- Measure solenoid resistance
- Check for battery voltage at the solenoid with ignition on
