APPLICABILITY: 2019-21MY Crosstrek PHEV
SUBJECT: DTC P0452 EVAP System (CPC) Pressure Sensor/Switch Circuit Low Design Changes to Fuel Tank Assembly & Vent Tubes

 

INTRODUCTION:

This bulletin announces design changes made to the fuel tank and vent tubes. An enhanced material has been incorporated into the production of these components. If DTC P0452 is stored in the engine control module (ECM), the information in this bulletin MUST be used to ensure an accurate diagnosis. Fuel types with high alcohol (ethanol) content may react with the fuel tank resin and cause clogging within the fuel tank components. The new fuel tank and vent tubes use a material with increased resistance to alcohol.

 

PRODUCTION CHANGE INFORMATION:

The production change information for Crosstrek PHEV is TBD.

 

PART INFORMATION:

IMPORTANT NOTE: No design changes were made to the Circulate Tube or the Electronic Vent Solenoid.

Part Description Part Number
TANK COMPLETE-FUEL 42012FL061
TUBE-AIR VENT 42074FL791
TUBE-AIR VENT 42074FL801
TUBE ASSEMBLY 42074FL730
VALVE-VENT 42084FL380eBay

REMINDER: Always order the most up-to-date replacement parts based on the specific VIN being repaired.

 

SERVICE PROCEDURE / INFORMATION:

REMINDER:  Customer satisfaction and retention starts with performing quality repairs.

NOTE: Refer to the applicable Service Manual and review: General Description > Repair Contents > Action required before & after Battery Disconnect. Additionally, record any stored seat position(s) before proceeding. Relearn any seat position memory after work is complete. If the power rear gate (PRG) height has been customized, that position must also be noted and relearned.

 

STEP 1) Perform a fault scan and confirm DTC P0452 is stored in the ECM.

 

STEP 2) Check the data monitor. Is the value of the Fuel Tank Pressure Sensor -2.65kPa (-19.88 mmHg, -0.78inHg) or less?

No

With DTC P0452 detected, the circuit has returned to a normal condition at  this time. Reproduce the fault and repeat diagnosis.

Yes

Check the Tank Pressure Sensor power supply for short to ground (see wiring diagram provided below).

Connector & Terminal (AD93) No. 3 (+) – Chassis Ground (-):

Is the voltage 4.5 Volts or more?

No

Repair the harness and/or the connector.

Yes

Proceed to the next Step.

 

STEP 3) Check the harness between the ECM and the Fuel Tank Pressure Sensor for short to              ground.

Connector & Terminal (B134) No. 59 (+) – Chassis Ground (-):

Is the resistance 1 MΩ or more?

No

Repair the short to ground within the harness between the ECM and the Fuel Tank Pressure Sensor.

Yes

Proceed to the next Step.

 

STEP 4) Check for poor contacts. Is there a poor contact found within the Fuel Tank Pressure Sensor Connector?

No

Replace the Circulate Tube Assembly. Refer to the applicable Service Manual: ENGINE > FUEL INECTION (FUEL SYSTEMS)(H4DO)(HEV)) > Circulate Tube Assembly.

Yes

Proceed to the next Step.

 

STEP 5) Check the Fuel Tank Pressure Sensor Signal.

Connector & Terminal (AD94) No. 2 (+) – Chassis Ground (-):

Is the voltage 2.2V or more?

No

Replace the Circulate Tube Assembly.

Yes

Proceed to the next Step.

 

STEP 6) Perform Electronic Vent Solenoid inspection.

Refer to the applicable Service Manual: Engine > EMISSION CONTROL (AUX. EMISSION CONTROL DEVICES)(H4DO(HEV)) > Electric Vent Solenoid Valve Assembly > Inspection.

Is the resistance between terminal 1 & 2 approximately 34Ω and all the connections secure?

No

Replace the Electronic Vent Solenoid:

Refer to the applicable Service Manual: Engine > EMISSION CONTROL (AUX. EMISSION CONTROL DEVICES)(H4DO(HEV)) > Electric Vent Solenoid Valve Assembly.

Visually inspect the internal condition of the Evaporative Line connections to the Electronic Vent Solenoid:

  1. Resin Tube on the Fuel Tank Assembly (attached directly to the Vent Solenoid)
  2. Vent Tube #1
  3. Vent Tube #2

If any deposits/build-up is found inside the tube(s), replace all the Vent Tubes and Fuel Tank Assembly.

Yes

Proceed to the next Step.

 

STEP 7) Inspect the evaporative system lines, hoses, and tubes for any deformation, cracks, or any     other physical damage. Replace any affected items as necessary.

IMPORTANT NOTE: Whenever reconnecting the ground cable terminal to the battery sensor, torque to 7.5Nm (5.5ft.-lbs. or 66inch-lbs.) while supporting the sensor with the other hand as outlined in the applicable Service Manual under: STARTING/CHARGING SYSTSEMS > Battery Sensor.

Smoke Machine Automotive Leak Detector,Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles
  • 【Why Need It】For example: 1. The rupture of the vacuum hose will cause the mixture to be too thick, the idle speed will increase, the hot car will not start well, the engine will surge during acceleration, the fuel consumption will increase significantly, and the exhaust pipe will emit black smoke. 2. Blocking will cause the idle speed to drift, and the idle speed is easy to stall. 3. Air leakage in the vacuum tube will cause the engine to run weakly
  • 【No Air Pump】1. The AUTOOL SDT103 smoke leak detector doesn't come with an internal air pump, so you'll need to connect it to an external workshop air source and a 12V vehicle power supply to bring in the workshop air.2. Turn the flow control dial of the AUTOOL SDT103 smoke leak detector counterclockwise to open the airflow, and then switch on the power at the back of the device. This will start the AUTOOL SDT103 machine, generating smoke. (When adding smoke oil to the AUTOOL SDT103 smoke leak detector, make sure not to exceed 20 ml, and please use baby oil or paraffin oila).
  • 【External Flow Meter】You can easily control the air pressure, because the air pressure of each pipe in the car is different. If the air pressure is too high, the pipe will be damaged, and if the air pressure is too low, the leak will not be detected. Therefore, the flow meter is very important to protect your detection system more effectively. Make testing safer
  • 【EVAP Detection】American cars that began production in 1996 are equipped with EVAP service ports; in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models may be located in other locations. Open the plastic cover of the EVAP service port, then use the spool wrench to remove the check valve clockwise, then install the EVAP service port adapter, and introduce smoke from the port into the EVAP leak detection system.
  • 【Wide Testing Range】The smoke leak detector can do smoke testing of multiple systems, such as EVAP systems, Intake Systems, Cooling / EGR /Exhaust Systems, Crankcase Systems, Engine Airtightness, Vacuum Leaks, Low Pressure Turbo leaks.Applicable cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks and speedboats boats.
