Subject: | Diagnostic Trouble Code (DTC) P1441 (EVAP Canister Purge Solenoid Flow During
Non-Purge) and/or Hard Start or Extended Crank After Adding Fuel (Replace EVAP
Canister Purge Solenoid) |
Models: | 1998 Saturn vehicles |
Condition
The vehicle may exhibit a DTC P1441 and/or hard start or extended crank condition
immediately after fuel fill.
Cause
Some EVAP canister purge solenoids may stick open, which may cause the DTC to
set and/or a hard start condition immediately after a fuel fill. Fuel vapors generated
during a fuel fill may leak past the EVAP canister purge solenoid and into the intake
manifold causing this hard start condition.
Correction
Refer to the following procedure to repair this condition.
Procedure
- Connect a Scan tool to vehicle.
• | If using a Tech 2, run the "EVAP Service Bay Test" on EVAP
system. Observe the "EVAP CP Valve Leak" status. If "EVAP CP Valve
Leak" fails, the EVAP canister purge solenoid may be stuck open. |
• | If using the PDT, run "EVAP Service Bay" on EVAP system. Observe
the "Purge Leak" status. If "Purge Leak" status fails, the
EVAP canister purge solenoid may be stuck open. |
- Verify that no DTCs other than P1441 are stored. If any other DTCs are
stored, refer to the proper diagnostic chart in the service manual.
- Position vehicle on hoist and raise vehicle.
- Disconnect EVAP canister purge solenoid vacuum source (hose
to intake manifold), and connect a vacuum tester to the EVAP canister purge solenoid
and apply vacuum.
• | If the EVAP canister purge solenoid holds vacuum, refer to System Diagnosis
in the service manual. |
• | If the EVAP canister purge solenoid does not
hold vacuum, the solenoid is stuck open. |
- Replace the EVAP canister purge solenoid.
