Key on, engine running. Within VCM Live, open the MAP sensor DTC parameter, does the MAP sensor parameter display a voltage more than 4.9 volts with the engine running below 3,000 rpm? |
≥ 4.9 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 0.1 volts or less? |
|
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 5v reference splice SP6. 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 SP3. 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 stored codes. Does the engine operate without any stored DTCs? |
