Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.

WARNING:

Refer to: Fuel and Evaporative Emission Pipe Warning

CAUTION:

Refer to: Clean, Dry, Low Pressure Gas Source Caution

Ignition - On / Vehicle - In Service Mode
Verify DTC P0641 is not set.
- If the DTC is set
  Refer to: DTC P0641, P0651, P0697, or P06A3
- Go to next step: If the DTC is not set
Verify the following conditions do not exist:
- Evaporative Emission Canister - Restricted/Visible Damage
- Evaporative Emission Hose - Kinked/Restricted/Visible Damage
- Evaporative Emission Pipe - Kinked/Restricted/Visible Damage
- If a condition exists
  Repair or replace as necessary.
- Go to next step: If no condition exists
Disconnect the component: Quick Connect Fitting@Q12 Evaporative Emission Purge Solenoid Valve
Install - CH-52519 EVAP Service Port Access Tool - Between: Evaporative Emission Canister Purge Tube & Q12 Evaporative Emission Purge Solenoid Valve
Install - GE-41413-A / B Evaporative Emissions System Tester (EEST) - Hose@ CH-52519 EVAP Service Port Access Tool
Ignition - On / Vehicle - In Service Mode
Perform the following action:
1. Select - Nitrogen@ GE-41413-A / B Evaporative Emissions System Tester (EEST)
2. Press and release the switch: Remote Switch @ GE-41413-A / B Evaporative Emissions System Tester (EEST) - Special Tool = OnorActivated
  Use the tool to achieve a gauge reading of 9. 3 mmHg (5. 0 in H2O)
3. Verify the scan tool parameter: Fuel Tank Pressure Sensor & Gauge@ GE-41413-A / B Evaporative Emissions System Tester (EEST) = Within 1. 9 mmHg (1. 0 in H2O) of each other
- If not within 1. 9 mmHg (1. 0 in H2O) of each other
  Replace the component: B150 Fuel Tank Pressure Sensor
- Go to next step: If within 1. 9 mmHg (1. 0 in H2O) of each other
Perform the scan tool function: EVAP Purge/Seal - Venting
Verify the scan tool parameter: Fuel Tank Pressure Sensor = 0. 0 mmHg (0. 0 in. H2O) - The pressure should decrease quickly
- If not 0. 0 mmHg (0. 0 in. H2O) orDoes not decrease quickly
1. Ignition/Vehicle - Off
2. Verify the condition does not exist with the component and repair as necessary:
- Evaporative Emission Canister - Incorrect connection/Restricted/Visible Damage
- Evaporative Emission Hose - Defective/Incorrect connection/Kinked/Restricted/Visible Damage
- Evaporative Emission Pipe - Defective/Incorrect connection/Kinked/Restricted/Visible Damage
- Go to next step: If 0. 0 mmHg (0. 0 in. H2O) & Decreases quickly
Perform the following action:
- { Cap Type Fuel Fill } Remove - Fuel Tank Filler Cap
- {Capless Type Fuel Fill } Install - GE-41415-60 Engine Induction System Leak Test Adapter/Capless Fuel Fill Adapter @Door@Fuel Tank Filler Pipe
Ignition - On / Vehicle - In Service Mode
Verify the scan tool parameter: Fuel Tank Pressure Sensor = 1. 3 to 1. 7 V
- If not between 1. 3 and 1. 7 V
  Refer to: Circuit/System Testing
- Go to next step: If between 1. 3 and 1. 7 V
Verify the scan tool parameter: Fuel Tank Pressure Sensor = The parameter value should not change.
Perform the action while monitoring the parameter:
- Wiggle the harness and connector: B150 Fuel Tank Pressure Sensor
- Wiggle the harness and connector: K20 Engine Control Module
- If the parameter value changes
  Repair as necessary - Wiring / Terminal(s) / Electrical Connector(s)
- Go to next step: If the parameter value does not change
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Verify the DTC does not set.
- If the DTC sets
  Refer to: Circuit/System Testing
- Go to next step: If the DTC is not set
All OK.
