P1445 Troubleshooting

If this is the case with the code, you will be hearing very loud noises, like explosions, from the rear of the vehicle upon acceleration. Firstly check the carburetor to ensure that the fuel and air combination are properly balanced. If these settings are correct, then thoroughly inspect the distributor cap for any cracks or hairline splits, as this can produce a backfire. Move on to the spark plugs and ensure that they are clean and undamaged and inspect the engine gaskets for any sign of damage, as they are responsible for ensuring the correct gas exchange within the engine. P1445 OBD2 specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.
