What causes the P0108 code?The MAP circuit input to the ECU is too high problem may have several causes:The source of the problem is that the sensor range voltage input is higher than whatвЂ™s required by the ECU, generally above 5 volts.The most common problem is a bad MAP sensor.The wiring or connector may be bad or have a bad connection, or could be too close to higher voltage consumption components, especially alternators, ignition wires, etc. This means that the voltage input to the ECU is too high and that it is not in the correct range for proper engine operation to work with inputs from the Mass Air Flow Sensor (MAF) and Throttle Position Switch (TPS). Manifold Air Pressure (MAP) Barometric Pressure Sensor Circuit High Voltage Input Problem What the P0108 code meansP0108 is the code for a problem with the MAP electrical circuit sensor having too high voltage input to the Engine Control Unit ( ECU). 2010 ISUZU 4HK1TC Engine For Sale. 2007 ISUZU 6HK1X Engine For Sale.Perhaps best known for their three modern series of trucks, The N-Series Gas, N-Series Diesel, and F-Series Isuzu trucks are also widely known for some of their older truck models as well.

The vehicle will most often not run well, idle poorly, accelerate erratically, have excessive fuel consumption, or backfire because the MAP sensor and throttle position sensor are not operating together. The ECU could also be bad but that is rare.P0108 code will be generally preceded by the Check Engine Light coming on the dashboard instrument display. 5 to 5 volts.If the engine is not in good condition, is missing, has poor fuel pressure, or has an internal issue with the engine like a burned valve, these things can prevent the MAP sensor from getting a correct output. A poor electrical ground can cause problems also.The sensor itself may be simply operating out of range from age or damage to the sensorвЂ™s internal components.MAP sensors must operate within specific ranges to send correct signals for the ECU to coordinate with the throttle position sensor so it can adjust correctly for proper engine operation.

5 out at idle, and a maximum of 5 volts to the ECU. Then reset the fault codes and perform a road test with a scanner attached with live data streaming.If the P0108 code comes back, then follow the test procedure.Check the MAP sensor voltage, which is normally 5 volts in and. What repairs can fix the P0108 code?The most common potential repairs to address the P0108 code are as follows:Verify the code with a scanner. The MAP sensor high voltage output issue can cause excessive fuel consumption, rough operation, backfiring, difficulty starting in certain circumstances, and can cause other damage if continued to be driven.Often times, if the Check Engine Light came on immediately at startup, then the OBD- II system can be reset and the vehicle will operate normally. How serious is the P0108 code?The P0108 code will result in poor running of the engine and requires immediate attention. Idle voltage is normally 1 to 1.5 volts and full throttle is usually around 4.5 volts.Do not buy a new MAP Sensor or ECU unless it is clearly at fault.

This is why it is important to verify the fault and reset it before doing any repairs.YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. If all checks are good, then a final test to determine if the ECU is bad must be done.Additional comments for consideration regarding the P0108 codeMany vehicles with mileage over 100,000 have momentary sensor problems that usually occur during start up or prolonged stress situations on the drive train.If the Check Engine Light comes on and the vehicle seems to be operating normally, the OBD-II system can be reset using the scanner and the problem may not reoccur. Then check the voltage output on the MAP sensor to see if it is in the correct range.At this point it is necessary to determine if the MAP sensor is defective and if it has no or incorrect output, then replace the sensor. Disconnect the electrical connector and then reinstall it to ensure a fresh electrical connection.
