What is the stopwatch on the Ford EVAP system?

What is the stopwatch on the Ford EVAP system?

Fig. 3 on page 22 shows a simple example of the integrity process. The CPS and CVS are both closed, sealing the gas vapor system. The FTPS shows −7.0 in.-H 2 O and the stopwatch represents the countdown timer inside the PCM.

When to turn off the EVAP system monitor?

EVAP SYSTEM MONITOR PRETEST CONDITIONS Engine running with the ECT signal over 176ºF; then ignition switch turned off. Engine started (cold): Requires a key “off” period of 8 hours. The key-off period can be shortened to 3 hours using the Scan Tool factory “Bypass Procedure”. MIL is off. No Emission related DTC’s are present

What should I do if my catalyst monitor stops running?

The first and foremost step is to check whether the engine light is off. If your vehicle has active trouble codes, it may stop a monitor from running completely. 2. Check if your Vehicle has a Coolant Temperature

When does EVAP turn off the ignition switch?

EVAP SYSTEM MONITOR DRIVE CYCLE INSTRUCTIONS Do not turn off the ignition switch during the test procedure. All Onboard Diagnostic Monitors are cleared when the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the Scan Tool.

Are there any problems with the Ford Escape?

See all problems of the 2010 Ford Escape . The contact owns a 2014 Ford Escape. While attempting to drive the vehicle, the instrument panel failed to illuminate and the digital odometer failed to function. The vehicle was not taken to a dealer or an independent mechanic for diagnostic testing.

What are the enabling conditions for an EVAP test?

But before the test can begin, many enabling conditions must be met. In addition to the CPS, CVS and FTPS being fully operational, the mass airflow (MAF), intake air temperature (IAT), vehicle speed (VSS) and engine coolant temperature (ECT) sensors, plus a variety of engine management sensors, must be fault-free.

What happens when the CPS goes negative on a Ford?

If the pressure continues to go negative, the PCM concludes that the CPS may not have fully closed, and sets a P1450. At this point, the test would be aborted. The PCM is also looking for any changes in engine load and fuel slosh, either of which can affect the test results.

How is the evaporative gas vapor integrity test done?

The evaporative gas vapor integrity test is performed in several phases. But before the test can begin, many enabling conditions must be met.

What do you need to know about the CA smog test?

Exhaust Gas Recirculation Valve and System. Engine ignition timing setting. LPFET Low Pressure Fuel Evaporative Test. Ignition timing will be inspected. Ignition Timing. Proper ignition timing degree is required. Gas cap test. EVAP Test. Fuel cap functioning properly. Failed check engine light.

What causes a car to not pass the smog test?

OBDII “Readiness Flags” Test: Your 1996 and newer car, truck, van, SUV, or motorhome will not pass the smog test if certain “readiness flags” are not set. Some “check engine” related failures don’t illuminate the check engine light, but do cause smog check failures.

How is a functional inspection conducted in a smog test?

The functional inspection is conducted by the smog technician and is hands-on. The smog technician will ensure proper operation of the following emissions components and systems. Your vehicle’s engine ignition timing will be inspected during the smog test.

Can a car pass the emissions test after a reset?

A slight chance of passing the emissions test after a reset exists, but it is very slim. The trick is to get your vehicle smog checked before your engine computer detects the check engine light illuminating trouble code, and only after the required readiness flags have set.

Where is the AC condensate drain in a Ford F-150?

Foul odor when running AC. Think the drain tube is plugged. I bought a can’t find the drain tube/hole. They are usually under the passenger side of the vehicle. If the drain was plugged, you should have wet floor boards on the passenger side.

How does the first phase of the EVAP system work?

The first phase is the workhorse side of the gas vapor system and is designed to purge the gas vapors that have been collected in the charcoal canister. The PCM commands the CPS open with the engine running, and gas vapors are purged using the intake manifold vacuum.
