Symptom: P1296-NO 5 VOLTS TO MAP SENSOR When Monitored and Set Condition: P1296-NO 5 VOLTS TO MAP SENSOR When Monitored: During power-down and battery voltage greater than 10.4 volts. Set Condition: The MAP sensor signal voltage goes below 2.35 volts with the key off for 5 seconds. POSSIBLE CAUSES 5 VOLT SUPPLY CIRCUIT MAP SENSOR MAP SENSOR WIRING HARNESS INTERMITTENT PROBLEM MAP SENSOR 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND PCM (5-VOLT SUPPLY) TEST ACTION APPLICABILITY 1 Note: If the PO107 - MAP Sensor Voltage Too Low is also set, diagnose it first t in Sensors, read the MAP sensor voltage.. Is the voltage below 2.35 volts? All Yes → No → 2 Turn the ignition off. All Yes → No → Repair the 5 Volt Supply circuit. 3 Turn the ignition off. t in Sensors, read the MAP Sensor voltage. Is the voltage above 4.5? All Yes → Replace the MAP Sensor. No → 160 DRIVEABILITY - GAS |
