If knock sensors fail, knock control is switched off and the ignition angle is retarded slightly since a cylinder allocation is no longer possible.
Engine will continue to run without Camshaft Position (CMP) sensor signal and can also be restarted:
-
When a malfunction is recognized, the Engine Control Module (ECM) initiates one ignition spark per cylinder for each crankshaft rotation.
-
The offset of one engine rotation will have no noticeable effect on the injection quality. Instead of occurring with intake valves open, injected fuel
will be "pre-loaded" (in front of closed intake valve). This has only a minor effect on the quality of the mixture preparation.
Checking activation
-
If installed, slide back the rubber boot on the connector for the Camshaft Position (CMP) sensor, but leave the connector connected.
