Light engine stay on when water temperature needle indicator is in the middle, engine works OK, and car too.


The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

A flashing check engine light is an indication of a severe misfire or problem that is likely to harm your engine. Immediate diagnosis and service is needed.

Some specific causes for the light to be on are:

Gas cap left off, not tightened, not installed correctly, or needs to be replaced

02 sensor

Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups

At start up for a bulb check - Should not stay on

Problem in the emission system, including clogged exhaust or the catalytic converter not functioning properly

Dirty/clogged air filter

Dirty MAF sensor

There are pages and pages of items that can cause a check engine light to come on. Having it checked with a scan tool will narrow down the problem area.

My speedometer stopped working ,my abs light stays on and my check engine light stays on and the brake light stays on


Check the "tone wheel" and magnetic pickup that sends the signal to the speedo, also to the ABS, and possibly integrated into the brakes for brake light.

It is one magnetic pickup that controls these three lights. As far as Engine goes, get the car to an Autozone (if it is safe to drive) and they will check all your codes, including check engine, with their scanner for free and identify the location of the problem for you for FREE!.

Hope this helps.

Have a 1996 Isuzu Trooper LS, check engine light came on so I checked it with a scanner and it said generic code PO 133, which is a slow response, or slow switching so I put an oxygen sensor on, check...


I had the same thing. It is something to do with emissions apparently. I was told to check the fuel cap ! I put some silicone on the seal, cleaned it up, put it back on with the correct number of clicks and after about 15 minutes of driving, the Check Engine light stayed off.

I have a 97 nissan maxima, it was serviced in february but the service light stays on. why is the service light staying on?

Engine management light on rac scan shows fault (P0115 eng coolant sensor) I have replaced and fitted new sensor light stillv stays on does it need resetting via a computer


Yes the light will have to be reset. If you cant reset by disconnection the battery for a couple minutes you will need to have it done with a scanner. Also usually its not the sensor that throws the code. Its usually a stuck open thermostat. If you have a gauge look to see if its been running on the colder side lately. Sometimes the engine will warm up normally but going down the freeway it will cool off to about 160 degrees when in fact its should be around 200 degrees. A scanner will show this while driving if you only have a idiot light. This is a sign of a bad thermostat
