If the P0107 code comes back, then follow the test procedure.Ĭheck the MAP sensor voltage in and out along with the electrical connector and wiring. Reset the fault codes and then perform a road test. The most common repairs to address the P0107 code are as follows:
Often times, if the Check Engine Light came on immediately at start up, then the OBD- II system can be reset and the vehicle will operate normally. Occasionally, if no problems are found, the technician can reset the fault codes and then retest. The MAP sensor issue can cause excessive fuel consumption, rough operation, and difficulty starting in certain circumstances, and can cause other problems including engine damage if continued to be driven. Have the code diagnosed as soon as possible. The P0107 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.ĭo not buy a new MAP Sensor or ECU unless it is clearly at fault. The technician must verify the voltage output of the MAP sensor is in the correct range and fluctuates with the engine speed and has proper voltage. First, follow the test procedure in the diagnosis to ensure there is the correct voltage to the sensor and from the sensor to the ECU. Common mistakes when diagnosing the P0107 codeĭiagnostic errors are largely due to not following the prescribed procedure. If the voltages are correct within the proper range, then it is most likely a bad MAP sensor and needs replacement. With the engine running at idle, it should have minimum 1 volt on the input to the ECU and then increase with engine speed and load. If the code comes back, then the mechanic will need to do a voltage test with the key on using a multimeter and verifying there is 5 volts input to the MAP sensor and a minimum of. He can observe this by watching data live on his scanner while driving. A qualified mechanic should then reset the OBD-II fault codes and road test the vehicle to see if the code comes back. P0107 is diagnosed with an OBD-II scanner. How does a mechanic diagnose the P0107 code? The engine can go into a limp home mode which means it automatically reduces power to protect the engine until the code can be diagnosed and repaired. The vehicle will most often not run well, idle poorly, accelerate erratically, have excessive fuel consumption, and backfire because the MAP sensor and throttle position sensor are not operating together and giving false input to the ECU. P0107 code will be normally preceded by the Check Engine Light coming on the vehicle dashboard display. The ECU could also be bad but that is rare. 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 having a correct voltage output. MAP sensors must operate within specific ranges to send correct signals for the ECU to coordinate with the throttle position sensor to adjust correctly for proper engine operation and may have other codes associated with P0107. The sensor itself may be simply operating out of range from fatigue of the sensor’s internal components. A poor electrical ground can cause problems also. which results in incorrect output voltage. 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. The most common problem is a bad MAP sensor. The source of the problem is the sensor range voltage input is less than required by the ECU. The MAP circuit for low voltage problem may have several causes: 5 volt or less which means that it is not in the correct lower range for proper engine operation. This means the voltage input to the ECU is. P0107 is the general code for a problem with the MAP circuit sensor having too low voltage input to the Engine Control Unit (ECU).
