Conditions for Running the DTC
- The ECM monitors the CKP sensor while the engine is cranking. The ECM uses the CMP sensor to determine if the engine is cranking. If DTC P0341 or P0342 is set, the ECM then monitors the manifold absolute pressure (MAP) sensor signal to determine if the engine is cranking.
- The engine is cranking.
- DTC P0337 runs continuously when the above conditions are met.
