Diagnostic Trouble Code (DTC) P0107
Manifold Absolute Pressure Sensor Low Voltage
What is the circuit like?
QUESTION- WHEN DOES THE DTC SET?
ANSWER- This DTC can be stored in "key-on" status.
Here are the two tabulated cases when the DTC sets:
CASE A |
CASE B |
1) The engine is idling. |
1) When the engine part is in load. |
2) No throttle position (TP) sensor MTIA fail conditions are present. |
2) The engine revolution speed is < 4,000rpm |
3) Engine speed (rpm) is < 2,500rpm. |
3) No Throttle Position (TP) Sensor fails conditions are present. |
4) The MAP is < 12.0 kPa. |
4) The Throttle Position (TP) angle is > 30.0. |
- |
5) The MAP is < 11.5 kPa. |
- |
6) An open or low voltage condition exists. |
MORE ABOUT THE SETTING AND CLEARING OF DTC
MEASURES TAKEN WHEN DTC SETS |
WHEN WILL DTC CLEAR? |
1) The Malfunction Indicator Lamp (MIL) is seen glowing. |
1) The MIL will turn off automatically after four repetitive ignition cycles in which the diagnostic runs flawlessly. |
2) The ECM is enabled to record operating conditions when the diagnostic fails and this information will be stored in the Freeze Frame and Failure Records will buffer. |
2) A history DTC will unset after 40 consecutive warm-up cycles. |
3) A history DTC is stored |
3)The Scan Tool will clear all DTCs. |
4) The ECM substitutes a fixed MAP value |
4) Disconnecting the ECM battery feed for more than 10 seconds |
5) The ECM uses TP to control the fuel delivery (the scan tool will not show anything now) |
