2009 TROUBLE CODES

my ultra gage gave me the following codes: P 043 E, P 043 F, P 2401, P 2402, & P 2419. where do i find out what these codes mean?

 

Reset the codes, make sure your gas cap is on properly and see if they come back. If they do you will need to check the items listed as trouble areas below.

P043E Reference orifice clogged Leak detection pump creates negative pressure through reference orifice, and EVAP system pressure measured to
determine 0.02 inch leak criterion. 0.02 inch leak criterion measured at start and at end of leak check. If system pressure lower than -4.85 kPa (-36.38 mmHg)*, ECM determines that reference orifice has clogging malfunction.

P043F Reference orifice high-flow Leak detection pump creates negative pressure through reference orifice, and EVAP system pressure measured to
determine 0.02 inch leak criterion. 0.02 inch leak criterion generated at start and at end of leak check. If system pressure higher than -1.06 kPa
(-7.95 mmHg)*, ECM determines that reference orifice has high-flow malfunction.

Trouble areas to look at:

• Canister pump module
• Connector/wire harness (Canister pump module - ECM)
• ECM
• Leakage from EVAP system

P2401 Leak detection pump stuck OFF Leak detection pump creates negative pressure through reference orifice, and EVAP system pressure measured to determine leak criterion. 0.02 inch leak criterion is measured at start and at end of leak check. If system pressure higher than -1.06 kPa (-7.95 mmHg)*, or lower than -4.85 kPa (-36.38 mmHg)*, ECM determines
that leak detection pump stuck OFF.

P2402 Leak detection pump stuck ON Leak detection pump creates negative
pressure through reference orifice, and EVAP system pressure measured to
determine leak criterion. If system pressure higher than -1.06 kPa (-7.95 mmHg)*, or lower than -4.85 kPa (-36.38 mmHg)*, ECM determines that leak detection pump stuck ON.

Trouble areas to look at:

• Canister pump module
• Connector/wire harness (Canister pump module - ECM)
• ECM
• Leakage from EVAP system

 

jimmy, thanks for the info. very much appreciated.

 

jimmy, do you happen to know if these related parts are covered by the federal emissions warrantee for 10 years blah blah miles?
