Component Testing
WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, and 2010 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Static Test
- Ignition OFF, remove the Camshaft Position Actuator Magnet.
- Test for 5.0-9.0 Ω between the solenoid control terminal 2 and the low reference terminal 1 at the Camshaft Position Actuator Magnet.
- If not within the specified range, replace the Camshaft Position Actuator Magnet.
- Test for infinite resistance between each terminal of the magnet and the magnet housing.
- If not the specified value, replace the Camshaft Position Actuator Magnet.
Dynamic Test
- Remove the Camshaft Position Actuator Magnet.
- The Camshaft Position Actuator Magnet pintle should be facing downward for this test.
- Do not allow electrical current to flow through the Camshaft Position Actuator Magnet for greater than 1-2 s.
- Install a 20 A fused jumper wire between the control circuit terminal 2 and B+. Momentarily install a jumper wire between the low reference terminal 1 and ground. The pintle should extent.
- If the function does not perform as specified, replace the Camshaft Position Actuator Magnet.
