You need to have it scanned for codes. Sometimes dodge will display the codes on the dash in the window for the odometer if you turn the key on, off, on, off, on, off, on with in five seconds.

SOURCE: failed smog cause check engine light

I can tell you for sure that all US models of the Ford Ranger came with a emission system that incorporated a MIL or check eng light, go to the dealer and have them run your VIN on the Ford on line information service, that will give you the engine Calibration of the emission system, you can then find out what emission system was used, export or US.

Turn off or rest check engine light to pass smog


It takes at least one "Good trip" stored in the computer before it will pass a smog check. Simply resetting the light did not fix the problem that caused the light to come on to begin with, and attempting to smog it will only result in a failed test.
You must address the fault first, then reset the system and drive upwards of 150 miles before a "Good trip" has been stored in the computer.

Why can't I pass smog check engine light won't come on


The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection.
You need to have the cause of your inoperative check engine light diagnosed and repaired.

1774 and 1775


There is probably no need to contact the BAR though you always have the right reserved. Trouble Code P1774 indicates your Mini's rear wheel speed sensor lost its signal, and trouble code P1775 indicates the right rear wheel speed sensor lost its signal as well. Both more than likely triggered during the dynamometer portion of the smog check inspection; while the front wheels are turning and the rear wheels are stationary. During this time, as far as the ABS system knows, the rear wheel sensors have lost their signals.
After a computer reset and driving your Mini Cooper for a few miles everything should return to normal, as apparently they have; and you've passed the smog check. Should the check engine light return in the near future for the same trouble codes P1774 and P1775 we'd recommend inspecting the rear wheel speed sensors for possible debris build-up. Since these trouble codes where triggered during the smog check and smog check machine failure we can assume the trouble codes were temporary and not related to any physical problem with your Mini Cooper.

Failed smog inspection due to fuel cap. SEEMS SO SIMPLE. AM I REALLY ONLY GOING TO REPLACE THE FUEL CAP?


Yes. The evaporative emission system is comprised of a cannister to capture and store gas vapors, a purge valve solenoid that opens when certain engine conditions are met, and purges the vapors from the cannister to be burned in the combustion process rather than being released into the atmosphere, A key component of this system is the plain, old ordinary gas cap. If the cap was faulty it could cause problems in the evap system, which apparently caused you to fail the smog test. Hope this helped and best wishes.
