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, P0108, P2122, P2123, P2127, P2128, P2138 or P2610 are not set.

* The engine is running.

* Time between current ignition cycle and the last time the engine was running is greater than 10 s.

* Manifold pressure between 50-115 kPa (7.25-16.68 PSI).

* BARO pressure between 50-115 kPa (7.25-16.68 PSI).

* Turbocharger boost pressure between 50-115 kPa (7.25-16.68 PSI).

* This DTC runs continuously within the enabling conditions.

Conditions for Setting the DTC

The ECM detects an inconsistency between pressure sensors in the induction system in which a particular sensor cannot be identified as the failed sensor. The difference is greater than 10 kPa (1.5 PSI).

Action Taken When the DTC Sets

DTC P00C7 is a Type B DTC.

Conditions for Clearing the DTC

DTC P00C7 is a Type B DTC.

Circuit/System Verification

1. Ignition ON, verify that DTCs P0106, P0107, P0108, P2122, P2123, P2127, P2128, P2138 or P2610 are not set.

• If a DTC is set
If a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.

• If no DTC is set

2. Ignition ON, verify the following scan tool parameters are within range of the Altitude vs. Barometric Pressure table. Refer to: Altitude Versus Barometric Pressure Altitude Versus Barometric Pressure table.

* BARO Sensor

* MAP Sensor

* Turbo Boost Sensor

• If a sensor parameter is not within range
Refer to the appropriate diagnostic below for further diagnosis.

• Barometric Pressure (BARO) Sensor. Refer to: DTC P2227-P2230 P2227

• Manifold Absolute Pressure (MAP) Sensor. Refer to: DTC P0106 P0106

• Turbocharger Boost Pressure Sensor. Refer to: DTC P0236 P0236

• If all sensor parameters are within range

3. All OK
