Fist thing is ..any dash warning indicators..light a Service Engine Soon" light?

Emissions controls and sensors are monitored by your vehicles on board computers... for their proper operation...which allows the vehicle to run as clean and efficient as possible.

You need to check for logged OBDII diagnostic fault codes.

Some Auto Parts stores offer this service free of charge. Check your local shops for free code reading. You may find some codes, which will provide a starting point.

Could be as simple as a O2 sensor.

Headlight warning buzzer not working on 2006 toyota celica

  • 1 Turn the ignition key to the "II" position.

  • 2 Check the lights on the dash. You should see a variety of dash lights light up. One of those lights will be a "Check engine" light. This light should stay lit with the ignition key in the "II" position. The rest of the lights should go out. If the "Check engine" light begins to blink, you may have a problem with one of the vehicle's electronic components. Consult your owner's manual or call your dealership for possible servicing issues.
  • 3 Start the engine. The "check engine" light should go out after a few seconds. If it does not, this can indicate either a maintenance interval has been reached or a more serious problem with the vehicle's emissions control system. Again, it is advised to consult your owner's manual or call the dealership for service.
  • 4 Check for an illuminated "SRS" light on the dash. The SRS light indicates a problem with the supplemental restraint system, i.e., the airbag, on the Camry. This needs to be serviced by a professional mechanic.
  • 5 Check for an oil light on the dash. The oil light is in the shape of a small oil canister. When this lights up, it indicates low oil pressure. Low oil pressure is caused by a blockage in the system, a weak oil pickup or oil pump, or low oil levels in the engine. Check and see if your Camry is overdue for an oil change. It is recommended that the oil be changed at 5,000 miles or every six months.
  • 6 Check for the low fuel warning. The fuel light on the Camry is on the fuel gauge near the "E" on the gauge face. The low fuel light means that you have to refuel your vehicle.
  • 7 Check for the seat belt warning light. The seat belt warning light is a picture of a figure wearing a seat belt. If your seat belt is unbuckled, then this light will illuminate (along with a warning chime) indicating that you should buckle up.
  • 8 Check for an orange car with lights on (on the dash lights). This warning light indicates that one or both of your brake lights has failed, or the electrical resistance in the bulb filament indicates that it is about to fail and will need service soon.

    Trubleshooting p0502 honda element

    P0502 is a Vehicle speed sensor issue:
    P0502 Description The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.

    speed_sensor.gif Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
    - Speedometer may not work properly
    - Transmission shifting problem Possible Causes - Vehicle speed sensor harness or connectors is open or shorted
    - Vehicle speed sensor
    - Combination meter
    - Faulty ECM.

    Noticed that warning light on my dashboard is showing service Engine soon confirmed that it is my speed sensor is faulty. how many sensors are on the vehicle and want to replace them.

    This is a new one the engine service light is on and its caused by teh speed sensor?? this is a totally new fault showing and iam wondering how you learnt the speed sensor is the cause ,unfortunatly their is no listing for resetting a mitsubishi service light in my alldata book so it looks like its a dealer only job although i bet its possible on this older vehicle somehow ,like holding the trip meter on and then turning the ignition on or the AM/fm button the radio or something equally bizarre

    Service engine soon

    hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.
