P1106 Ford Code - Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage
Quick Answer
The Manifold Absolute Pressure (MAP) sensor responds to pressure changes in the intake manifold. Common causes include 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. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1106 Ford Description
- 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.
What are the Possible Causes of the DTC P1106 Ford?
- Faulty Manifold Absolute Pressure (MAP) sensor
- Manifold Absolute Pressure (MAP) sensor harness is open or shorted

Frequently Asked Questions about P1106 Ford Code
1. What are the common symptoms of OBDII code P1106 in a Ford vehicle?
- Common symptoms include poor engine performance, decreased fuel efficiency, stalling, rough idling, and potential issues with acceleration.
2. What can cause the Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage fault code in a Ford vehicle?
- Possible causes could be a faulty manifold absolute pressure (MAP) sensor, damaged wiring or connectors in the MAP sensor circuit, or a problem with the engine control module (ECM).
3. How can I diagnose the cause of the high voltage issue related to the MAP sensor circuit?
- A thorough inspection of the MAP sensor, wiring, and connectors is recommended. Testing the sensor's voltage output and checking for any visible damage to the components can help pinpoint the problem.
4. Can a dirty or clogged MAP sensor trigger the P1106 fault code in a Ford?
- Yes, a dirty or clogged MAP sensor can disrupt the sensor's readings, leading to intermittent high voltage issues and triggering the P1106 code.
5. What are some DIY repair tips for addressing the P1106 code in a Ford vehicle?
- DIY repair tips include cleaning the MAP sensor with specialized sensor-safe cleaner, inspecting and repairing any damaged wiring or connectors, and resetting the fault code to see if the issue persists.
6. Is it safe to continue driving with the P1106 fault code present in a Ford car?
- It is not recommended to continue driving with the P1106 fault code, as it can lead to further engine problems and potential damage if left unresolved.
7. How much does it typically cost to repair the Manifold Absolute Pressure Sensor Circuit Intermittent High Voltage issue in a Ford vehicle?
- The cost of repair can vary depending on the specific cause of the fault, but it may range from $100 to $300 for parts and labor.
8. Can resetting the vehicle's ECM help clear the P1106 fault code temporarily?
- Resetting the ECM may temporarily clear the fault code, but if the underlying issue causing the high voltage problem is not addressed, the code is likely to reappear.
9. Will the check engine light turn off on its own after repairing the P1106 fault in a Ford car?
- In most cases, once the underlying issue triggering the fault code is resolved, the check engine light should turn off automatically after a few successful drive cycles.
10. Is it advisable to seek professional help for diagnosing and repairing the P1106 fault code in a Ford vehicle?
- If you are not confident in diagnosing or repairing the issue yourself, it is highly recommended to seek professional help from a certified mechanic or Ford dealership to ensure proper diagnosis and repair.
