I had my 1999 Honda Accord LX engine oil changed by a small shop yesterday, and smelled some burning smell last night when parting it in garage. Today, the check-engine light is on when I drive. The engine oil seems in the correct level, but the light is on. Can you let me know what's the problem?

The check engine light has nothing to do with oil change. Are you sure it isn't the maint req light? It is the same color and on the left bottom side of the dash.

You can reset this light by holding in the trip indicator button and turn the ket on. When the light stops flashing it is reset.

If it is the check engine light (it has a car image)and it is on, then you must have it reset with a device. Most parts houses have a free reset computer.

Let me know

Thanks, losone. I actually took the car back to the shop, and they scaned using a hand-held device and found out that two of oxygen sensors are dead. The shop asked for $400 for changing the sensors, but I am not sure if they will use good-brand parts. I am not sure if I can replace the sensors by myself. Thanks a lot.

They are not difficult to replace, I question them both going out. You could start with the top one and see what materializes. I have bought acceptable ones on ebay for as little as $30 each. Worked fine but he only issue I had was the wiring but that really isn't all that difficult.

Thanks. I bought two sensors from Auto zone for about $200, which are ready for wiring. I will try DIM. Thanks.

I had both of Oxygen sensors replaced and the light reset, but the check-engine light turns on again after the engine starts running a couple of minutes. Anyone knows what's gping on with the light? Thanks a lot.

I was a little wary of replacing both O2 sensors. The rear on is bullet proof. I have never replaced one.

You need to find what code it has set. I suspect it is an emission code. They are hard to track because of so many components in the emission system and the code is sort of generic to a number of items.

Sometimes a rich engine condition will set an O2 sensor code.

Let me know what code was set. Good Luck

I was asked to replace the 2 O2 sensors by that small shop, anyway.

I checked with Auto Zone, where they let me use the device to find out the code. It is P1167, saying Manfacurer contrl, Fuel Air Metering. Then I took my car to another repair shop. Thye checked it again, and got the same code P1167. The shop's computer says that "Primary Hearter Oxygen Sensor (Sensor 1) Heater System Malfunction. But the shop's repair manual (hardcopy) indicates" Fuel injector, fuel pressure, etc". It seems a fuel system problem?

Any suggestions are apprecaied.

It sounds like the code for a fuel presure regulator. It's the small metal object on the fuel rail with a vacuum hose. Remove the hose with the engine running and see if it makes a difference. If not then it is the regulator. Let me know
