P1106 FORD - Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage
P1106 FORD Possible Causes
- Faulty Manifold Absolute Pressure (MAP) sensor
- Manifold Absolute Pressure (MAP) sensor harness is open or shorted
- Manifold Absolute Pressure (MAP) sensor circuit poor electrical connection
First diagnose P1106 FORD code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
Cost of diagnosing the P1106 FORD code
Labor: 1.0The cost of diagnosing the P1106 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the P1106 FORD code detected?If the Powertrain Control Module (PCM) detects a Manifold Absolute Pressure (MAP) sensor signal voltage that is intermittently high, the P1106 code will set.
P1106 FORD Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1106 Ford DescriptionThe Manifold Absolute Pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:
- 5-volt reference circuit
- Low reference circuit
- MAP sensor signal circuit
The Powertrain Control Module (PCM) supplies 5 volts to the MAP sensor on the 5-volt reference circuit. The PCM also provides a ground on the low reference circuit. The MAP sensor provides a signal to the PCM on the MAP sensor signal circuit which is relative to the pressure changes in the manifold. The PCM should detect a low signal voltage at a low MAP, such as during an idle or a deceleration. The PCM should detect a high signal voltage at a high MAP, such as the ignition is ON, with the engine OFF, or at a wide open throttle (WOT). The MAP sensor is also used in order to determine the barometric pressure (BARO). This occurs when the ignition switch is turned ON, with the engine OFF. The BARO reading may also be updated whenever the engine is operated at WOT. The PCM monitors the MAP sensor signal for voltage outside of the normal range.
