| SYMPTOM/CONDITION: NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 2.0L DOHC/SOHC (NATURALLY ASPIRATED), 2.4L, 3.3L, 3.5L, OR 3.8L ENGINE. |
| DISCUSSION:If a vehicle exhibits a no-start due to failure of the cam or crank sensor,
the opposite sensor may be reported as the DTC (ie. bad cam sensor sets crank sensor DTC
and vice versa).The faulty sensor may generate a signal strong enough (at key
"ON") to be interpreted by the controller as a legitimate signal. Since the
engine is not running, the opposite sensor will not be generating any pulses. The
controller, expecting corresponding pulses from both sensors,matures a fault for the
sensor that is not generating any pulses. In this case, the good sensors reported as
faulty. To verify which sensor is at fault, use the DRB l l l and select DRB l l l Standalone, 19941998 Diagnostics, select Engine system, select Monitor Display, and No Start monitor.Under the No Start monitor the cam and crank sensors should display a no response or LOST on the display. If a sensor is reporting a signal at key "ON", it should be replaced. |
