Circuit/System Verification
- Ignition ON, observe the DTC information with a scan tool. DTC P0069 should not set.
- Compare the scan tool MAP sensor pressure parameter, and the scan tool BARO sensor pressure parameter, to the pressure parameter of a known good vehicle. Both readings should be within 3 kPa of the known good vehicle.
- Compare the scan tool MAP sensor pressure parameter, and the scan tool BARO sensor pressure parameter, to the reading in the table. Both parameters should be within the specified range indicated on the table.
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
IMPORTANT:
The vehicle used for the comparison is not limited to the same type of vehicle being serviced. A vehicle known to provide an accurate reading is acceptable.
IMPORTANT:
The Altitude vs Barometric Pressure table indicates a pressure range for a given altitude under normal weather conditions. Weather conditions consisting of very low or very high pressure and/or very low or very high temperature may cause a reading to be slightly out of range.
