Monitor the fuel tank pressure sensor voltage either with the scanner or using at voltmeter (Green/Orange wire pin 33 at the Electronic Control Module). The fuel tank pressure sensor should have approximately 5 volts on the Red wire (pin 44) and a ground on the Blue/Black wire. With atmospheric pressure on the system, the voltage on the Green/Orange wire should be near 2.5 volts. • 2. Next ground the canister close valve Blue/Black wire, this should close the valve and seal the system. • 3. With the engine idling, locate the purge control valve (under the throttle body, inline of the vacuum hose) and tap the Yellow/Orange wire to ground while watching the fuel tank pressure sensor voltage. Bring the voltage down to near 1 volt and stop tapping the ground. The voltage should hold if there are no leaks. If the voltage starts to rise pinch off the hose between the canister and the fuel tank. If the voltage stops rising the leak is in the canister, canister close valve or hoses. • • Subscribe here: https://goo.gl/j1pCfn • Connect with me: • FaceBook: https://goo.gl/rKg2Bv • Grease Monkey Art Gallery https://greasemonkeygallery.com/ by The Flat Rate Mechanic • Instagram: https://goo.gl/NCjRhM • Google Plus: https://goo.gl/6AyJz3 • Website: http://flatratemechanic.com • For Promotional offers, consulting, training, sponsorships or other inquiries contact me at [email protected] • The Flat Rate Mechanic. 25 year ASE Master Automotive Technician and Advanced level ASE certified • The Flat Rate Mechanic is a participant in the Amazon Influencer Program. #p0442 #EVAPLeak #FlatRateMechanic Check out The Flat Rate Mechanics Tool Store on Amazon https://goo.gl/M8MpdC nbsp; • nbsp: • Disclaimer: • Due to factors beyond the control of The Flat Rate Mechanic, it cannot guarantee against unauthorized modifications of this information or improper use of this information.
