This is typically telling you that the pollution control system thinks there may be a problem.
There are oxygen sensors and Engine coolant temperature sensors that tell the computer what air/fuel mixture to use.
If the computer does not like the information that it is getting, it turns on the light, and stores a fault code that a mechanic can access.
Hint........ if the light is on steady, it's usually not a big deal.
If the light is flashing, there could be a serious problem.
Time to talk to a service center.
A warning light, such as a check engine light or MIL, indicates that a fault is present. You need a diagnostic tool to see what code is present in that system, and the simplest solution is to take the car into a dealership or shop for repair.
ESP (electronic stability program) and the ABS (anti-lock brake system) are the same system, you must have the system tested by the dealer when the light is on, it requires a special scanner to read the fault code that is present when the warning lights are on.
to reset engine warning light simply turn key on without starting slowly depress gas pedal to floor 3 times in about 5seconds wait 15sec then shut off key...this is in the owners manual under engine check warning light.but also may want to have someone plug a obd2 code reader into the plug under center of dash under steerind wheel....code readers cost around $100 at canadian tire or other such part stores..this reader will tell you what trouble codes if any are present in your vehicles computer.hope this helps..
P0296 Cylinder 12 Contribution/Range Fault
Is triggered when the Power Train Control Module (PCM) detects that the acceleration rate of the crankshaft for Cylinder #12 was less than a calibrated amount. During normal conditions the PCM turns the Fuel Injectors ON and OFF in the Fuel Injection System. Symptoms: - Engine Light ON (or Service Engine Soon Warning Light) - Engine Misfire - Engine Run Rough - Low MPG
P0298 - Engine Oil Over Temperature Condition Indicates the Engine Oil Temperature Protection (EOT) strategy in the Power Train Control Module (PCM) has been activated. This temporarily prohibits high engine speed operation by disabling injectors, reducing the risk of engine damage from high engine oil temperature. Note: On engines which are equipped with an oil temperature sensor, the PCM reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.
Symptoms: - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of Power - Engine Surge
P0298 is set when the vehicle has been running below 1,000 rpm and less than 20 mg/stroke MFDES with EOT sensor signal reading above 110C (230F). The time to set the fault is dependent on EOT and Intake Air Temperature (IAT) temperatures, and can vary between approx. 15 to 45 minutes
Possible Causes: - Very high engine RPM for an extended period of time. - Overheating condition. - Malfunction EOT sensor or circuit (vehicles w/EOT sensor).
Possible Solution: 1. Inspect EOT sensor circuitry at sensor and PCM. Inspect for damage, loose or pushed-out pins, loose or poorly crimped wires 2. If connectors are ok check cooling system, radiator, fan/clutch operation, thermostat 3. If cooling system is ok carry out KOEO On-Demand Self Test 4. If other fault codes are present after test repair them, if only P0298 is present clear codes 5. Let vehicles sit for 8 hours and then KOEO 6. Monitor EOT in live data 7. If EOT sensor reading is above 110*C(230*F) replace sensor 8. IF EOT is below 110*C check continuous memory DTCs 9. If P0298 is present replace PCM
came on because of a problem as to which problem there are 100s of codes first check and make sure gas cap is on securely if good then have car scanned most auto stores such as auto zone/advanced auto[check ur local area] offer this service for free the trouble code will give u the area and or component that needs repair or replacement
1998 volvo s40 right hand drive: there is an orange triangle light with green in the center and an upside "y" in the center of the two. It is between the "up orange arrow" and "a an orange car with an X on it" the light comes and stays on. Dont know what it means. can you help. Thanks
