|What are the Possible Causes of the P1107 JAGUAR Code?

  • 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

|How to Fix the P1107 JAGUAR Code?

Start by checking 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 connector's pins.

|What is the cost to diagnose the P1107 JAGUAR code?

Labor: 1.0

The cost to diagnose the P1107 JAGUAR code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P1107 JAGUAR code detected?

If the Powertrain Control Module (PCM) detects a Manifold Absolute Pressure (MAP) sensor signal voltage that is high, the P1107 code will set.

|What are P1107 JAGUAR code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)

|What Does the P1107 JAGUAR Code Mean?

The 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.
