How do I get my EVAP system monitor ready?
How do I get my EVAP system monitor ready?
Start the engine and idle for four minutes, then drive in stop-and-go traffic for five minutes using smooth accelerations and decelerations. Stop and idle for 4 minutes. The EVAP monitor should be complete.
What causes EVAP monitor not ready?
As a rule, the EVAP monitor only runs when certain conditions have been met. If these conditions have not been met since the last time the monitor ran, or since the last time the battery was disconnected, or since the last time fault codes were cleared from the PCM memory, the EVAP monitor will NOT be ready.
How do you complete a Ford drive cycle?
Stop vehicle and repeat without overdrive to 64 Km/h (40 MPH) cruising for at least 30 seconds. While at 64 Km/h (40 MPH) , activate overdrive and accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop for at least 20 seconds and repeat step 10 five times. Executes the transmission portion of the CCM.
How many miles does it take to reset an EVAP system?
Here’s something you probably don’t know: after clearing the car’s computer you will need to drive for about 50 to 100 miles. As you drive your car the computer will monitor all the sensors and register the results.
What does the CVS do on a Ford EVAP system?
Ford’s Evap System: Operation & Testing. The CVS is a basic on/off-open/closed solenoid that’s normally open when deenergized. The PCM uses the CVS to seal the gas vapor system for leak integrity checks. The FTPS is a three-wire pressure transducer that’s used to measure pressure changes in the gas vapor system.
When does the EVAP monitor not run?
When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be “bypassed” and the P1000 cleared.
How do you check for a gas vapor leak in a Ford?
In 2005, Ford began phasing in a different method to check for .020-in. leaks. The system is called an engine off natural vacuum (EONV), and primarily uses the CVS and FTPS after the vehicle is shut off to check the gas vapor system.
