E041

TEST CONDITIONS
1. Code EO12 not set;
2. Reference pulses being received;
3. RPM less than or equal to 1600.

FAILURE CONDITIONS
No cam reference pulses being received for 5 seconds.

ACTION TAKEN
1. ECM turns on "Engine Control System Fault" telltale;
2. ECM commands BCM to display "Service Soon" message on Driver Information Center (DIC).

DESCRIPTION
The cam sensor is located on the distributor shaft and provides one pulse per rotation of the distributor. The ECM uses the cam sensor signal to know the location of the camshaft for proper fuel distribution.

Code EO41 sets when the ECM knows the engine is turning (reference pulses being received) and does not detect any cam sensor pulses.

Notes on Fault Tree
1. This trouble tree requires the use of four jumper wires using terminal P/N 1201483 and 12014837.

Notes on Intermittents
Manipulate affected wiring while the engine is running. if the fault is induced the code will set and the wiring should be repaired for an intermittent open or short to ground.

Disconnect and reconnect the distributor connector and ECM connector and ensure they are latched.
