P0107 Isuzu Code - Manifold Absolute Pressure Sensor Low Voltage
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure 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 P0107 Isuzu Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAP Sensor voltage is less than 0.15 V for greater than 13 ms.
What are the Possible Causes of the DTC P0107 Isuzu?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

The code P0107 indicates a low voltage condition in the Manifold Absolute Pressure (MAP) sensor circuit.
2. What are the common symptoms of a P0107 code in an Isuzu vehicle?
Common symptoms of a P0107 code include poor engine performance, rough idling, stalling, and a decrease in fuel efficiency.
3. What are the possible causes of a P0107 code in an Isuzu?
Possible causes of a P0107 code include a faulty MAP sensor, damaged or corroded wiring in the sensor circuit, vacuum leaks, or issues with the engine's air intake system.
4. How can I diagnose a P0107 code in my Isuzu?
To diagnose a P0107 code, you can use an OBDII scanner to read the code and check the voltage output of the MAP sensor using a multimeter. Inspect the sensor and its wiring for any visible damage.
5. What is the repair process for a P0107 code on an Isuzu?
The repair process for a P0107 code may involve replacing the MAP sensor, repairing or replacing damaged wiring, fixing vacuum leaks, or addressing any other underlying issues causing the low voltage condition.
6. Can driving with a P0107 code in an Isuzu cause further damage?
Continuing to drive with a P0107 code may lead to reduced engine performance and fuel efficiency. It is recommended to address the issue promptly to prevent any potential long-term damage.
7. How much does it typically cost to repair a P0107 code in an Isuzu?
The cost of repairing a P0107 code can vary depending on the specific cause of the issue, the labor rates of the repair shop, and the cost of parts. It's advisable to get a diagnostic from a qualified mechanic for an accurate estimate.
8. Are there any DIY tips for troubleshooting a P0107 code in an Isuzu?
You can start by checking the MAP sensor's wiring connections for any loose or damaged wires. Inspect the sensor for any signs of physical damage or corrosion. However, for a thorough diagnosis and repair, it's best to consult a professional mechanic.
9. Can a P0107 code in an Isuzu be triggered by a loose gas cap?
A loose gas cap typically triggers evaporative emission-related codes, not a P0107 code related to the MAP sensor. It's important to focus on diagnosing the specific issue causing the low voltage in the MAP sensor circuit.
10. How long does it take to repair a P0107 code on an Isuzu?
The repair time for a P0107 code can vary based on the exact cause of the issue and the complexity of the repair. Simple fixes like replacing the MAP sensor may take less time, while diagnosing and addressing wiring issues or vacuum leaks could require more time.
