Laymans terms

This code means that the car's computer is having trouble keeping track of the engine's moving parts. It's like when a clock's hands don't move together correctly.

Explanation

The engine control module (ECM) detects a loss of synchronization between the crankshaft and camshaft signals.

Technical description

The P033F code is triggered when the ECM detects that the signals from the crankshaft position sensor and the camshaft position sensor are not aligned as expected. This misalignment can affect engine timing and performance.

Symptoms

• Engine misfires

• Poor acceleration

• Check Engine Light on

Common Causes

• Faulty crankshaft position sensor

• Faulty camshaft position sensor

• Timing chain or belt issues
