There are benefits to using an auto repair shop. When using an auto repair shop, the price will go up due to labor costs. This price is depending on if you replace it yourself and the price of your specific vehicles part. In the case of P0456, it is a small leak, less than. Fixing a P0455 can cost anywhere between 20 - 250 to replace an EVAP vent valve. If the EVAP system does not maintain the pressure, the ECM recognizes an EVAPorative emission control leak. The onboard test procedure pulls a small vacuum on the fuel tank system and then looks for any leakdown, so the least little CRACK in a hose can cause failure codes, replace the hoses with dealer parts and you will probably be good to go B. The Powertrain Control Module (PCM) monitors the purge vapor ratio and the Evaporative System Integrity Monitor (ESIM) Switch closed ratio. I hope this ihelps, and let me know if you need more assistance with this.ĬAVITY CIRCUIT FUNCTION 1 K342 16BR/WT (EXCEPT DIESEL) ASD CONTROL OUTPUT 2 A405 18RD/DB FUSED B(+) 3 A941 18RD FUSED B(+) 4 - 5 A104 20YL/RD (6.7L A/T) FUSED B(+) 6 A310 16RD/LB (EXCEPT BASE) FUSED B(+) 7 C15 14DB/WT (EXCEPT BASE) REAR WINDOW DEFOGGER CONTROL OUTPUT 8 F12 14PK/RD FUSED IGNITION SWITCH OUTPUT (RUN-START) 9 T16 16YL/OR (EXCEPT DIESEL M/T) TRANSMISSION CONTROL OUTPUT 10 - 11 X22 18GY/LB HORN CONTROL OUTPUT 12 W3 18BR/WT WIPER LOW SPEED CONTROL OUTPUT 13 Z971 18BK GROUND 14 C16 18DB/GY (EXCEPT BASE) HEATED MIRROR CONTROL OUTPUT 15 A212 20RD/OR (5. During the leak test, the ECM closes the vent control valve and purge valve to seal the EVAPorative system. The monitor is a two stage test and runs only after the Evap system passes the small leak test. C10 on the TIPM is the light gray 22 way connector. If the switch opens or was open before the test began, the monitor passes. This is a power down test that runs at key-off when the PCM sees 0 rpm’s, the purge solenoid is energized for a maximum of 30 seconds, venting any vacuum trapped in the evaporative system. The test lamp should respond to the command. Command the EVAP canister purge solenoid valve to 50 percent with a scan tool, or the EVAP canister vent solenoid valve ON and OFF. Ok, I looked up G107, and it is the ground eyelet that is attached to the inside right fender close to the hood hinge. The ESIM switch stuck closed monitor checks to see if the switch is stuck closed. Ignition ON, verify that a test lamp illuminates between the voltage supply circuit terminal A and ground.
