Cars are monitored by onboard "computers". The check engine light is telling you something is wrong, but isn't telling you what. There are all kinds of codes that are stored in this "brain", and it has to be hooked up to another computer to find out what the codes are.

This is what makes me mad about newer cars. I am used to working on older, more simple cars. It will cost you anywhere from $80 on up just to have it scanned to find out what's wrong. If you are lucky, you might find a parts store that does it for free. Around where I live, Autozone and O'reilley/Schucks will do it free.

All that will do is scan for the code and tell you what's wrong....hopefully. Then ya gotta fix it.

There is no way anyone can tell you what's wrong without a computer-scanner.

2001ford ranger engine light flashing, vehicle lightly shakes when idle, decrease in acceleration, gas cap seal tightly, no leaks, no indicating sounds-such clanks, tings, bangs


A blinking service engine light indicates an engine miss. Take your car into any/most parts house and they will use a code reader/scanner to see which code number is being set and then identify your engine cylinder that is not functioning properly. Once you identify the cylinder you can start to check different systems, spark plug, wires, injectors,ect. to find your problem and fix the miss.

Fuses ok,light in dash tested and works. But check engine light does not come on when you turn on the ignition. What else should I check? This is a ford ranger XLT 4x4 4.0L V6-245cid engine (pushrod)


The instrument cluster (10849) carries out a display proveout to verify that all warning/indicator lamps and monitored systems are functioning correctly. When the ignition switch (11572) is in the ON position with the engine (6007) off, the following indicators will illuminate:
  • CHECK ENGINE/malfunction indicator lamp (MIL).
  • CHECK GAGE warning indicator.
  • Charge system warning indicator.
  • Anti-lock brake warning indicator (ABS).
  • Safety belt warning indicator (60second proveout).
  • Air bag indicator.
  • An indicator is inoperative - CHECK ENGINE/malfunction indicator lamp (MIL)
  • Bulb.
  • Circuitry.
  • Instrument cluster printed circuit.
  • Powertrain control module (PCM) (12A650).
  • GO to Pinpoint Test N .

Warning light check engine light turns on, sometimes after 10-20 minutes drive. The engine is perfectly OK. Indicator light is off after the car has "rested" during the night.


You may have a sensor malfunction. Have a mechanic run the codes and see if there are any stored in the computer. Just because the engine runs OK now does not mean it will continue to do so. The reason the light goes off after the vehicle has set over night may be due to the vehicle not sensing the issue after the long passage of time, until you begin driving again.

Ntlworld.commalfunction indicator light came on car came to a hault but started ok book says exhaust related fault


When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this code, you may begin diagnosis.

Check engine light, and engine temp gauge drops. Otherwise car is running well.


If the thermostat is stuck open, the engine temperature will drop and set a fault code indicating that the engine is not reaching operating temperature. This will cause your check engine light to come on. Have someone scan your engine computer. Most large parts chains will scan for codes at no cost to you. If there is a "Thermostat" or "Engine temp low in closed loop" or a similar code indicating low engine temperature, replace the thermostat.

Service engine soon light on my 2002 nissan xterra came on at about 100,000 miles. What could be the cause


If it's the indicator that literally says "service engine soon", and not the check-engine light, then you have no worries. That's programmed to come on at set intervals to remind you that routine service may be due soon (oil change, inspection, tire rotation, etc). It's not an indication of failure. Failures will be shown by the check-engine light. That one is nothing to worry about. Your owner's manual should have a procedure to turn it off.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance
