| DTC Descriptor |
DTC P00C7
Intake Air Pressure Measurement System - Multiple Sensors Not Plausible
| Circuit/System Description |
The Intake Air Pressure Measurement System consists of (3) sensors, the barometric pressure (BARO) sensor, the manifold absolute pressure (MAP) sensor, and the Turbo Boost sensor.
| Conditions for Running the DTC |
| • |
DTCs P0106, P0107, P0236, P0237, P0238, P2227, P2228, P2229, P2230, or P2610 are not set.
|
|
| • |
Ignition ON after greater than 10s since last ignition cycle.
|
|
| • |
The BARO, MAP, and Turbo Boost signals are between 50-115 kPA (7-17 psi).
|
|
| • |
This DTC runs continuously when the above enabling conditions are met.
|
|
| Conditions for Setting the DTC |
The ECM detects greater than 10 kPA (1.5 psi) difference between all (3) of the Intake Air Pressure Measurement System sensors.
| Action Taken When the DTC Sets |
DTC P000C7 is a Type B DTC.
| Conditions for Clearing the DTC |
DTC P000C7 is a Type B DTC.

| Circuit/System Verification |
| 1. |
Ignition ON, observe the DTC information with a scan tool. Verify that DTCs P0106, P0107, P0236, P0237, P0238, P2227, P2228, P2229, or P2230, are not set.
|
|
| 2. |
If a DTC is set, refer to
Diagnostic Trouble Code (DTC) List - Vehicle
for further diagnosis.
|
|
| 3. |
Ignition ON, observe the scan tool MAP Sensor, BARO Sensor, and Turbo Boost Sensor parameters. Compare the parameters to the
Altitude Versus Barometric Pressure
table.
|
|
| 4. |
If one or more sensor parameters are out of range, refer to the appropriate diagnostic for more information.
