Early Production (SBEC)

Test 1 - 2:

Test 3 - 7:

SYMPTOM
P0108-MAP SENSOR VOLTAGE TOO HIGH

WHEN MONITORED
Engine speed between 600 to 3500 RPM. TP sensor voltage less than 1.2 volts. Battery voltage greater than 10 volts.

SET CONDITION
The MAP sensor signal voltage is greater than 4.96 volts for 1.7 seconds.

POSSIBLE CAUSES
- MAP sensor voltage above 4.6 volts
- (K1) MAP sensor signal circuit shorted to (K6) 5-volt supply circuit
- (K1) MAP sensor signal circuit shorted to battery voltage
- MAP sensor internal failure
- (K1) MAP sensor signal circuit open
- (K4) sensor ground circuit open
- PCM
