P1107 Isuzu Code - MAP Circuit Intermittent Voltage Low

Quick Answer

The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). 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 P1107 Isuzu Description

The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.The MAP/BARO Switch solenoid valve switches it's air flow passage according to the voltage signal sent from the ECM.

Frequently Asked Questions about P1107 Isuzu Code

1. What does OBDII code P1107 for Isuzu MAP Circuit Intermittent Voltage Low indicate?

Code P1107 indicates that the Manifold Absolute Pressure (MAP) sensor circuit is detecting intermittent low voltage readings, which can affect engine performance.

2. What are the common symptoms of Isuzu OBDII code P1107?

Common symptoms of P1107 may include rough idling, reduced engine power, poor fuel efficiency, and in some cases, stalling or difficulty starting the vehicle.

3. What are possible causes of Isuzu OBDII code P1107?

Potential causes of P1107 can include a faulty MAP sensor, damaged wiring or connectors in the MAP sensor circuit, vacuum leaks, or issues with the intake manifold.

4. How can I diagnose the P1107 code on my Isuzu?

Diagnosing code P1107 typically involves checking the MAP sensor's wiring and connectors for damage, inspecting the intake manifold for leaks, and testing the sensor's voltage output using a multimeter.

5. Can I drive my Isuzu with OBDII code P1107?

It is not recommended to drive your Isuzu with P1107 for an extended period since the issue can lead to poor engine performance and potential further damage if left unaddressed.

6. How can I repair OBDII code P1107 on my Isuzu?

Repairing P1107 often involves replacing a faulty MAP sensor, repairing damaged wiring or connectors, fixing any vacuum leaks, or addressing issues with the intake manifold.

7. Is resetting the OBDII code P1107 sufficient to fix the issue?

Simply resetting the code may temporarily clear the check engine light, but it will not resolve the underlying problem causing P1107. It's important to diagnose and address the root cause of the issue.

8. Can a dirty MAP sensor cause OBDII code P1107 on an Isuzu?

A dirty MAP sensor can potentially cause erratic voltage readings that trigger P1107. Cleaning the sensor may help, but if the issue persists, it may need to be replaced.

9. Is OBDII code P1107 specific to certain Isuzu models?

While P1107 is related to the MAP sensor circuit, it can appear on various Isuzu models that are equipped with OBDII systems and MAP sensors.

10. How much does it typically cost to repair OBDII code P1107 on an Isuzu?

The cost of repairing P1107 can vary depending on the specific cause of the issue, but it may range from around $100 for a simple fix like a sensor replacement to several hundred dollars for more complex repairs involving wiring or manifold issues.
