Every sensor on the engine and transmission can cause the light to come on.

could be the O2 sensors. My 97 does that when I pull a trailer. Put it on the computer and 2 of the 4 sensors were slow to react

There are sensors all over the engine that can turn the check engine light on.

Upwards of 50 to 100. Depends on Year, Make, Model.......... See related questions below.

You must have an engine scanner to do that.

Then you may want to have a mechanic check it out.

There are many sensors that can trip the check engine light to come on.

No, diesels don't have O2 sensors.

Yes but the check engine light will be on.

it depends on the engine but check where the lower hose ends closest to the engine

If the check engine light is coming on periodically when hitting a bump in a 1995 Ford Taurus, perhaps a sensor is loose. Check both the oxygen sensors and the speed sensors on the transmission. Also check all sensors in the engine to make sure they are tight.

The check engine light is triggered by the Engine Control Module (ECM). The ECM receives information from many sensors and determines when to illuminate the check engine light.

If the check engine light it on a 2002 Hyundai Accent on one of the sensors is malfunctioning. The computer is acknowledging this and alerting the driver that there is a problem in the engine.

There are two sets of oxygen sensors on late model GM trucks. There are dual catalytic converters, one on each pipe coming off of the engine. In front of the catalytic converters are the first set of oxygen sensors. These sensors check the exhaust gases to see how the engine is performing. Based on the gases, the sensors send a signal to the computer telling whether to richen or lean out the air/fuel mixture. This insures optimal performance and fuel mileage. After the converters is another set of oxygen sensors. These sensors check the exhaust gases for cleanliness after having passed through the converters. These sensors don't directly affect engine function, instead they measure how well the converters are working. If a converter is no longer working properly or is clogged, they will lean out the engine so it will continue to function for a while, causing the 'check engine' light to come on. This is probably too much information, but I just wanted to be helpful. -Neal C.-

You will need a engine scanner to scan the engine. Some parts stores will do this for free.

You can not reset your oxygen sensors. You can only replace them. To reset the check engine light you will have to get that done by a repair shop with a computor. If replacing the sensors does not repair the problem then check for a vacuum leak.

Check: Coils, module & sensors

Faulty catalytic converter, or sensors in exhaust faulty

There is not one sensor. All the ECM sensors are tied to the check engine light.

I had all sensors replaced in my 03 Trailblazer and the check engine light stiil comes on. Why?

There are dozens of reasons. But in most cars of this model some sensors just become old and have to be replaced. When sensors fail ECU sets off the check engine light.

You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
