Circuit/System Verification
WARNING: This page is about a different variant/trim than selected.
- Verify there are no DTCs set related to the following component/system:
- B14A Automatic Transmission Output Speed Sensor
- B14C Automatic Transmission Input Speed Sensor
- B17 Barometric Pressure Sensor
- B26 Crankshaft Position Sensor
- B34 Engine Coolant Temperature Sensor
- B48 Fuel Temperature Sensor
- B65 Manifold Absolute Pressure and Intake Air Temperature Sensor
- B75 Mass Airflow Sensor
- Fuel System
- If a related DTC is set
- Go to next step: If a related DTC is not set
- Ignition - On / Vehicle - In Service Mode
- Verify the scan tool parameter: Mass Airflow Sensor = 0 to 2 g/s
- If not between 0 and 2 g/s
Refer to: DTC P0101
- Go to next step: If between 0 and 2 g/s
- If not between 0 and 2 g/s
- Engine - Running
- Verify the scan tool parameter: Mass Airflow Sensor = 5 to 40 g/s
- If not between 5 and 40 g/s
- Verify the following conditions do not exist:
- B75 Mass Airflow Sensor - Contamination of the measuring element/Water intrusion
- Intake Air Duct - Cracked/Leaking/Loose Clamps/Restrictions/Visible Damage
- If a condition exists - Repair or replace as necessary
- If no condition exists - Refer to: Particulate Filter Service Regeneration
- Go to next step: If between 5 and 40 g/s
- Verify the following conditions do not exist:
- B65 Manifold Absolute Pressure and Intake Air Temperature Sensor - Flow Restricted
- Q14 Exhaust Gas Recirculation Valve - Binding or Sticking
- If a condition exists
Repair or replace as necessary
- Go to next step: If no condition exists
- Verify a condition does not exist with the component: Exhaust System - Leaking/Missing components/Restricted - Refer to: Exhaust Leakage
- If a condition exists
Repair or replace as necessary
- Go to next step: If no condition exists
- If a condition exists
- Perform the following procedure/test: Cylinder Power Balance Test
Verify the procedure/test passes.
- If the procedure/test does not pass
Replace the component that failed the test: Q17 Fuel Injector
- Go to next step: If the procedure/test passes
- If the procedure/test does not pass
- Test or replace the component: B195A Nitrogen Oxides Sensor 1
