P0442 - Evaporative Emissions System Leak Detected (Small Leak)

P0455 - Evaporative Emissions System Leak Detected (Gross Leak)

This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum. If pressure does not increase, the ECM will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

Causes:
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
- Leak is in line between intake manifold

Solutions:
- Re-tighten or replace fuel tank filler cap
- Replace damaged or leaking EVAP canister
- Replace damaged or leaking lines.

P1443 - EVAP Control System / Vacuum System Purge Control Solenoid Or Purge Control Valve Fault. A fuel tank pressure change greater than minus (-) 7 inches of water in 30 seconds occurred with a purge (fuel vapor) flow at less than 0.02 pounds per minute.

Possible Causes:

Blocked fuel vapor hose between the EVAP canister purge valve and the FTP sensor.

Blocked fuel vapor hose between the EVAP canister purge valve and the engine intake manifold.

Blocked vacuum hose between the EVAP canister purge valve solenoid and the engine intake manifold.

EVAP canister purge valve stuck closed (mechanically).

Possible Solution:
Check for blockages between the fuel tank, the EVAP canister purge valve, and the engine intake manifold. Check for obstructions in the EVAP canister purge valve diaphragm and ports.

The canister is on the passengers side near the firewall if I recall correctly.

Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

Evaporative Emission Purge Solenoid

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

1. Disconnect electrical connector at solenoid.
2. Disconnect vacuum lines at solenoid.
3. Lift solenoid slot from mounting bracket for Removal & Installation.

To Install:

1. Position solenoid slot to mounting bracket.
2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
3. Connect electrical connector to solenoid.
   

Purge solenoid location:


EVAP cannister location:

Check the EVAP canister purge solenoid valve for being stuck open. Try to blow through it by mouth. It should be closed and should not be able to blow through it by mouth with it de-energized. Can test it per TSB # 01-025/05. Potential Causes: EVAP Canister Purge Control Solenoid Valve


There is a TSB for these and other possible trouble codes to be set due to a stuck open EVAP canister purge solenoid valve - TSB # 01-025/05. A stuck open EVAP canister purge solenoid valve will also allow fuel vapors from the fuel tank to enter the engine when the fuel tank is being filled - resulting in a hard start condition. The EVAP canister purge solenoid valve is under the hood on the drivers rear of the intake manifold area
