Conditions for Setting DTC P1107🔗
- Engine Running
- Manifold Absolute Pressure Sensor ≤ 0.73 psi
- The above must be present for a period of 128 instances/cycles or greater to trigger DTC P1107
Diagnostic Steps🔗
| Step | Action | Value (s) | YES | NO |
|---|---|---|---|---|
| 1 | - Key ON, Engine Running at full operating temperature - Within VCM Live, open the MAP sensor DTC Minimum parameter, does the MAP sensor parameter display 0.73 psi or less? |
Go to Step 2 | Intermittent Issue — Refer to Intermittent Diagnostics | |
| 2 | - Key OFF - Disconnect the MAP sensor connector - Key ON - Does the MAP sensor parameter within VCM Live display less than 0.5 psi? |
Go to Step 3 | Go to Step 5 | |
| 3 | - Probe the MAP ground connector cavity "A" (for Drive-By-Cable harness) cavity 2 (for Drive-By-Wire harness) with a test light connected to battery voltage - Does the test light come on? |
Go to Step 4 | Go to Step 6 | |
| 4 | - Check the MAP mechanical vacuum connection for correct mounting or any possible physical damage that may cause leakage - Any issues found? |
Go to Step 5 | Repair any issues found | |
| 5 | - Key OFF - Disconnect the ECU connector "C" and inspect the terminals for any physical damage or corrosion and contamination - Any issues found? |
Go to Step 6 | Repair the pins as necessary and circuit | |
| 6 | - Replace the MAP sensor - Is the repair complete? |
Go to Step 7 | N/A | |
| 7 | - 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 stored codes - Does the engine operate without any stored DTCs? |
System is now operational and ready to be tuned | Contact HP Tuners Support |
