What Does P0020 Mean?
The PCM has detected a malfunction in the intake camshaft position actuator solenoid circuit on Bank 2. This is an electrical circuit code — the Bank 2 equivalent of P0013 — indicating an open circuit, high resistance, or wiring fault between the PCM and the Bank 2 intake VVT oil control valve. The PCM cannot control intake cam timing on Bank 2.
Common Causes
35%
Disconnected or corroded connector at the Bank 2 intake VVT solenoid
30%
Failed Bank 2 intake VVT solenoid with open internal coil
20%
Broken or chafed wire in the Bank 2 VVT solenoid circuit
10%
Corroded PCM pin for the Bank 2 VVT control circuit
5%
Short to ground causing the PCM to detect a circuit fault
Diagnostic Steps
1
Locate the Bank 2 intake VVT solenoid and verify the connector is fully seated; inspect for corrosion or oil contamination in the connector
2
Measure solenoid coil resistance — expect 6.9-7.9 ohms at room temperature; an open reading means the solenoid must be replaced
3
Check for 12V supply at the solenoid connector with key on and verify PCM ground pulse on the control wire using a test light or voltmeter
4
Test harness continuity from the solenoid connector back to the PCM — less than 2 ohms on each wire confirms good wiring
5
Apply 12V directly to the solenoid to verify mechanical operation (should click and actuate); no response confirms internal failure

The most common cause of P0020 (Intake Camshaft Position Actuator Circuit / Open (Bank 2)) is: Disconnected or corroded connector at the Bank 2 intake VVT solenoid
Typical repair costs for P0020 range from $80 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Bank 2 intake cam timing defaults to base position. Expect reduced power, rough idle, and increased emissions. Safe to drive for short distances but repair promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0020 to identify the root cause.
