YES, connect pin 2 of the large conetor to the test plug, turn on the key but do not start it and the check engine light will flash once followed by the codes.
my 92 tempo had a yellow light service engine soon, i had a small computer under the hood replaced, that meters fuel to the car and was shutting off allowing to much fuel into the engine. the cost WA $245 usd but the problem was cured.AnswerThere is a way to get trouble codes, but it's not like otheres. I know Doge had cars/trucks you could access codes using the light & turning key to 'accessory' twice & then off. With the Tempo/Topaz, there is a 'pin' located in a small plastic box (diagnostic label) under the hood. With a multimeter, +lead, on pin, -lead to ground. But you'll still need a manual to be sure the right pin,(I can't describe it for sure), and to know what the codes mean. I guess the answer to the question is......'sort of'. AnswerOn the firewall, near the strut tower - depending on year and engine depends if it is on the passenger side or driver's side - you will find a connector that looks like a trapezoid. It should have a smaller connector (ground) next to it. It may also say "Self Test". There are six terminals on the larger and the smaller has only one. If you use a sweep hand (analog) multimeter for this procedure, use a piece of wire to connect pin 2 on the larger connector to the negative side of the voltmeter and then use the probe of the multimeter to connect to pin 4 of the large terminal. Make sure you set the voltimeter between 15 and 20 volts. Put the key on the ignition, turn the switch to on (but do not start) and watch the sweep hand do its thing. If everything works correctly it will sweep once pause and then sweep again. This is a Code 11. That means everything is good to go.
You can also purchase at most autoparts stores, small engine analyzers that do the same thing without the hastle of pesky wires. It also comes with a book that has all of the trouble codes. But the best thing is it covers most Ford vehicles from 1984-1994, at which time Ford changed from the EEC-IV electronic engine control system to a newer system. The cost for this analyzer is about $30.00. It is truly a must have in your tool collection. It will tell you exactly what is wrong with any electronic engine control problem on your vehicle.
The service engine soon, or check engine, light is reset with a scan tool after repairing the cause of the trouble codes.
you check the system for trouble codes.
Suggest you have it checked for trouble codes. The engine computer and airbag system should both have codes.
Have a dealer or mechanic check for "trouble codes". It's probably the oxygen sensor(s).
If you can not read codes with a scanner you have a wiring problem.
Possible speed sensor issue. Have it checked for trouble codes to know what to diagnose.
See link below for a complete list of trouble codes.
pretty much instantly. As soon as the codes are cleared the check engine light goes off and vice versa, unless there still is trouble. In this case the codes won't clear until the trouble is repaired.
you need to have the car's computer scanned to see what codes are making the service engine soon light appear.
The service engien light (check engine) comes on when the engine computer detects a malfunction and sets a code. You need to have the codes read, diagnosed and repaired to keep the light off.The service engien light (check engine) comes on when the engine computer detects a malfunction and sets a code. You need to have the codes read, diagnosed and repaired to keep the light off.
unless the battery has been disconnected, a history of previous codes is retained in memory and you will be able to tell why your service engine light was on earlier. disconnecting the battery erases all codes - you would have to wait until service engine light comes on again to read any recent codes. good luck!
A problem with the emission system. Need to have trouble codes checked.
The red Check Engine light and the amber Service Engine Soon light serve the same purpose. It is unlikely that a vehicle would have both. The trouble diagnostic codes have to be retrieved in order to determine if the problem is performance or emmissions related.
The Service Vehicle Soon indicator is usually a light bulb, headlight, or something to do with the vehicle. The Service Engine Soon indicator is anything that could be wrong with the Engine. Some computers can read codes for either, but some computers can only read codes for the Service Engine indicator.
Pending trouble codes: These are similar to normal trouble codes, but they are set after a single driving cycle, and usually before the check engine light is illuminated. Useful after repair work has been finished
After the Explorer is scanned for trouble codes to diagnose and then repair the malfunction , then the check engine light can be reset
The check engine light is reset with a scan tool after repairing the failure that caused the trouble codes.
If the check engine light is on with no codes, you have a wiring or computer issue.
Have it checked for codes, That is the same as the check engine light.
You need to have it checked for codes. If you fix the cause of the codes the light will stay off.
The best thing to do if to have a code reader hooked up and read the trouble codes the reader can also clear the codes once you have read them. If the problems aren't fixed the light will come back.
The check engine light comes on to indicate a possible problem with one of the engine's emission control systems. Take it in for service, and have the vehicle scanned for any trouble codes to locate the problem - usually a sensor.
The engine computer has detected a malfunction. You need to have the system checked for trouble codes.
You can't manually get the check engine light to give you the trouble codes on your vehicle. 1995 and later vehicles use the OBDII system and you must use a scanner tool to retrieve the codes. You can go to AutoZone or similar auto parts store that offers free scans to get the trouble codes retrieved. Or you can buy your own scan tool for about $70.
