The flashing check engine light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage. Replace a catalytic converter and have the engine checked as soon as possible by a certified mechanic.

Where is the Intake Air Temperature sensor located on a 2000 Jeep Cherokee?
it is in the intake manifold by the throttle body and the map sensor. it is a two wire sensor
Where is the heated oxygen sensor bank 1 sensor 1 located on a 2003 Saturn L200?
The oxygen sensorS that you are interested in are located in the exhaust manifold. (I'm assuming a V6 engine since most of the L-series Saturns I've encountered have all been the Ecotec V6)
Notice where the manifolds come together from each of the cylinders. You should see a device that screws into the exhaust manifold, near the junction. It screws right out but it might be a little difficult to break loose since it's been in a high temperature environment.
Depending on the replacement sensor that you use, you may have the plug in style or you may need to cut/splice the electrical of the new sensor.
An oxygen sensor tool is available that is open at the top to provide a place for the wire while you're working on the sensor.
It's a simple repair, just screw out the old one, put in the new one and connect it. Just make sure you get the wires right.
Even though the computer is only complaining about bank 1, sensor 1... replace BOTH of the front sensors at the same time. Really, it's worth the trouble since you'll be right back at it if you don't. You have 100,000 mile spark-plugs and very little to do for a tuneup on that engine, but the oxygen sensors should be considered an important routine maintenance responsibility.
the cause of this indicates one or more spark plugs,and/or coils need replacing

Disconnect the battery. BUT you should have it checked. There's a code stored in memory that is needed to fix the cause of the check engine light being on. If you do the battery thing, don't take it to a service tech and say fix it until the light comes back on.
How do you reset check engine light BMW z4?
The same as on all OBD-II compliant vehicles -- use a code reader's reset function. Disconnecting the battery is another way to reset check engine lights, but I do not recommend it on BMW's, as disconnecting the battery often messes with BMW's brains and require things such as the window functions to be reset/relearned.
What are trouble codes P0440 and P0441?
Evaporative Emission Control
System Malfunction This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines
, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine
P0441 Evap Emission Control System Incorrect Purge Flow
Where exactly is the check engine reset located under the steering wheel of a 1994 Geo Tracker?
Hi, Acording to the book I have, if you have a reset switch, it should be mounted under the left-hand side of the instrument panel. The way the picture looks, it should be right near the steering wheel. Yiu need to remove the panel under the steering wheel to get at it easily, that should be just a few screws. Good luck. Steve H.

The check engine light is telling you that there is something wrong with the engine monitoring system and the only way to shut it off for good is to have the codes read at the dealer or a parts store and repair whatever is wrong. Simply resetting the computer by unhooking the battery for a minute will only make it stop for a while until the computer can analyze the system and will not help you pass a smog check.
Yes it often causes the engine light to come on . You need to disconnect the battery for about two min then reconnect the battiery this will reset the computor, If it comes back on then you probly have a bad o2 sensor.
How can you tell if timing belt has been replaced on 1998 Ford Escort SE Sport?
Unfortunately you cannot tell for sure by looking. It may lookpretty goodand be ready to break. Fortunately this is not an interference engine. If it breaks you may be stranded but no engine damage will occur. The Ford 2.0L 4-cylinder (SOHC) engine requires inspecting the cam belt at 120,000 miles and replacing as necessary. If it looks great, you can risk it and not replace it. My advice would be to just replace it at 120,000 miles. If the car has over 120,000 on it already, take a good hard look at the belt. if you see no cracks or wear, it probably has been replaced.
