Hey Mike==It can but why guess. Go to Auto zone and have them check it our for free and you will know what is causing the light to come on. You can clean 02's but be sure the carb cleaner you use has NO silicone as it will ruin it for sure. GoodluckJoe

Try checking the gas cap. if it is not tight, the engine light tends to come on at random times

a check engine light that flashes while driving has nothing to do with the speed sensor or alternator a flashing engine light shows that there is problem that is causing catylitic conver damage for instance if you had a bad spark plug or spark plug wire that was causing a missfire then the light will flash there is no other reason for the light to flash

An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.

The temp sensor could make it start hard, is the OBD "check engine light" on? either way if your suspecting the temp sensor you should have it put on the scan tool and let it tell you if the sensor is within range or if it needs replacing

If the camshaft sensor is not operating properly, then the engine could suffer lower mpg. The sensor is what causes the engine to fire at the proper times and this is critical for better economy.

9 times out of 10 replacing the oxygen sensor will do the trick. Or, try disconnecting and reconnecting the battery.

some OBD 2 systems have a 4 wire 02 sensor if the o2 sensor is bad it will cause a stall, some times a break in a vacuum line will cause the same effect.

Mine came on on my 2001 Concorde because a rat got to the wires of a sensor, the little bastards did it three times :(

More times than not, it turns out to be the TPS sensor

What you are referring to is a MAF (mass air flow) sensor, not a map sensor. this regulates your air/fuel mixture and if clogged can affect your emissions control system and turn on the check engine light. Sometimes you can clean the MAF sensor and the problem will go away, other times you might need it replaced./

its probably your TPS Switch or your idle control sensor, check engine light will not come on for either take to Hyundai dealership

The Check Engine Light should be on if the sensor is faulty. The car may or may not hesitate, stall, or accelerate poorly. To read the engine error codes, cycle the ignition key from "off" to "on" three times: Turn the iginition key to the "on" position where the check engine light comes on but do not start the car. Turn the ignition key to off, then on, off, and on again and leave the key there. The odometer will read out any error codes. P0340 and P0344 are trouble codes for the camshaft position sensor.

It could be a loose gas cap often times. Autozone gives free diagnostic checks. If it could be a sensor. Take off the negative cable from the battery and place it back on the battery it will reset the check engine light.

start with engine off. press and hold that speedometer resetter while starting engine, check engine light will flash a few times then disappear.

Take it to a shop to have a diagnostic plugged into it. 9 times out of 10 its simply an oxygen sensor that has gone bad. When the diagnostic is complete it will tell you exactly why the check engine light is lit. Try to do this as soon as possible because it is affecting the miles per gallon in your vehicle.

In the units computer an algorithm is in operation looking at hours of engine operation, engine temperatures, speeds etc. From the sensor inputs the system calculates when to tell you to change the oil. The frequency of service depends on how many short trips are taken versus long trips and other combined sensor inputs. Once the car is serviced, turn the key on (do NOT start the engine), depress the gas pedal to the floor three times and the computer will be reset. If the light does not reset, repeat the procedure. Again do not start the engine as flooring the accelerator will race the engine and damage could occur.

The 1995 Chevrolet Geo flashing amber engine light is an indication that the engine needs to be checked soon. A red flashing engine light is an indication the engine needs to be checked immediately.

The Check Engine Light (CEL) will be on - there are diagnostic trouble codes (DTC) very specific to problems with the O2 sensor that indicate a failing sensor. Most times though, the DTC indicate other problems dur to the readings coming from the 02 sensors. See "Related Questions" below for more

It is important to know why a Check engine light blinks. In many cars, when it blinks so many times, it is indicating a code, which is indicating the problem number for the specific car.

it sounds like the oxygen sensor is bad or the throttle positioning sensor or even the mass air flow sensor. take the vehicle to an auto zone parts store or a checker store and they will read the code for free and you will know for sure. most likely it is the o2 sensor

Answering "I have 94 E320 I think the air mass sensor is not working I got the code with the blinking light and it blinked 7 times Please let me know if it is the code for air mass sensor Thank you?"

cycle the key three times and count the blinks of the check engine light
