DTC P0107 - Manifold Absolute Pressure Sensor Circuit Low
Conditions for setting dtc P0107
■ | Engine Running |
■ | Manifold Absolute Pressure Sensor ≤ 0.1 volts |
■ | The above must be present for a period of 128 instances/cycles or greater to trigger DTC P0107 |
Step |
Action |
Values (s) |
YES |
NO |
1 |
- Key on, engine running - Within VCM Live, open the MAP sensor DTC parameter, does the MAP sensor parameter display a voltage less than 0.1 volts with the engine running below 3,000 rpm? |
≤ 0.1 volts |
Go to Step 2 |
Intermittent Issue (Refer to Intermittent Diagnostics) |
2 |
- Key off - Disconnect the MAP sensor connector - Jump the 5 volt reference (Drive-By-Cable cavity "C" & Drive-By-Wire cavity "1") and reference pin (Drive-By-Cable cavity "B" & Drive-By-Wire cavity "3") together - Key on - Does the VCM Live MAP parameter display a voltage of 4.5 volts or greater? |
|
Go to Step 3 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced. |
3 |
- Inspect the MAP sensor and pins for corrosion, contamination or any physical damage. - any issues found? |
|
Repair the circuit as necessary, locate any wires that need to be repaired or replaced. |
Go to Step 4 |
4 |
- Key off - Disconnect the ECU connector "C" - Check for continuity between the MAP sensor connector signal (cavity "B" for DBC & cavity "3" for DBW) and the ECU signal pin C3-28 - Do you have continuity? |
|
Go to Step 5 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced. |
5 |
- Check for continuity between the MAP sensor connector 5v reference (cavity "C" for DBC & cavity "1" for DBW) and the ECU ground pin C25-C (for DBC harness) & pin C42-1 (for DBW harness) - Do you have continuity between them? |
|
Go to Step 6 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced. |
6 |
- Check for continuity between the MAP sensor connector ground signal (cavity "A" for DBC & cavity "2" for DBW) and the ECU ground pin C25-C (for DBC harness) & pin C42-1 (for DBW harness) - Do you have continuity between them? |
|
Go to step 7 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced. |
7 |
- Replace the MAP sensor - Is the replacement of the MAP sensor complete? |
|
Go to Step 8 |
|
8 |
- Clear any DTC from the ECU - Turn the ignition off and wait 30 seconds - Start the engine and operate the engine to full operating temperature - Observe the Check Engine Light on the Menu bar in VCM Live - After operating the engine within the test parameters, check for any store codes - Does the engine operate without any stored DTC's? |
|
System is now operational and ready to be tuned. |
