Open or short in the VVT solenoid wiring harness or connector (Bank 1 intake)
Faulty camshaft position actuator / VVT solenoid (Bank 1)
Poor electrical connection (corrosion, bent pins) at connector
Blown fuse or faulty relay supplying VVT/PCM circuits
Low engine oil level, dirty oil, or oil pressure problem affecting actuator operation
Faulty powertrain control module (PCM) or internal driver failure

Read freeze frame and live data with a scan tool: camshaft position, commanded actuator duty, engine RPM and oil temp
Visually inspect wiring and connector for Bank 1 intake VVT solenoid for damage, corrosion, or loose pins
Check engine oil level and condition; change oil if very dirty or low
Verify fuses and relays related to VVT/PCM power supply
Measure VVT solenoid coil resistance (compare to spec) and check for open/short
Backprobe connector with ignition ON to confirm battery voltage and PCM control signal (use scope if available)

Supply voltage at solenoid connector (ignition ON): approximately battery voltage (~11–14 V)
Solenoid coil resistance (typical range): ~6–30 ohms (manufacturer-specific — check OEM spec)
PCM output to solenoid: PWM duty cycle variable 0–100% to control oil flow
PWM frequency typical range: ~20–200 Hz (varies by manufacturer)
Open-circuit condition: infinite/high resistance (multimeter reads OL or >> specified coil ohms)
Short-to-ground/short-to-voltage detection: very low resistance (

Connect a scan tool, retrieve P0010 and any related codes, review freeze frame data and live PID showing commanded cam actuator status.
Check engine oil level and quality. If oil is low/dirty, correct and clear the code; retest.
Visually inspect the Bank 1 intake VVT solenoid connector and harness for damage, corrosion or disconnection.
With ignition OFF, disconnect solenoid and measure coil resistance with a multimeter. If open or out-of-spec, replace the solenoid.
With harness connected, turn ignition ON (engine OFF) and measure supply voltage at solenoid power terminal — should be near battery voltage. If absent, trace fuse/relay and power circuit.
Backprobe the control terminal while cranking or running to check for PCM control signal (use oscilloscope for PWM; a digital multimeter may show varying voltage). If no control signal but wiring and power are good, suspect PCM driver.
Perform continuity/resistance check between PCM pin and solenoid connector ground/power to locate opens or shorts. Wiggle harness during testing to find intermittent faults.
If available, swap the solenoid with the same component on the other bank (if identical) and see if code follows the component.
If wiring and solenoid check good but no PCM output, inspect relevant PCM fuses/grounds. If PCM driver confirmed faulty, consider PCM repair/replacement following OEM procedures.
After repair, clear codes and perform a drive cycle to verify the issue is resolved.

Damaged or disconnected connector at the camshaft actuator solenoid (Bank 1)
High resistance or broken wire between PCM and solenoid
Failed VVT solenoid coil (open circuit)
Contaminated or low oil preventing actuator movement (less likely to set 'open circuit' but can coincide)
PCM output driver shorted or open
