Cam Sensor Adjustment Procedure | ||||||||||||||
The sensor is a hall effect device with a rotating metal ring that is driven from the front of the cam gear via a shaft (like a distributor). This ring passes thru a grooved sensor molded into the sensor cap. The metal ring has a notch or window cut out of it. When the window goes by the sensor, the voltage drops, which tells the ECM where #1 TDC is. Jim Frankovich has done some measuring and calculating and has the following input:
Several people have found that when running a bigger cam with advanced valve timing, it sometimes will help cure a popping or sputtering symptom by advancing the cam sensor a few degrees. The above values give you an idea of what to shoot for. |
