I would greatly appreciate a list of check engine light codes for a 91 dodge spirit. I believe the code it put out was either: 1,2,4,7,5,5 3,4,7,5,5 This is for my girlfriends daughter, she was away at college and on the way home the check engine light came on. It is not overheating and the oil is fine. I think it is a O2 sensor but i would like to make certain since she is home for the weekend and i would like to make sure she has a safe trip back to school.

You can go to Advance Auto parts or Auto Zone and they will check the code for free. They can give you an idea from the code as what might be causing it.If the code comes and goes, It probably will probably not strand you.

Turn the key to run then off, back to run, then off, then to run and leave it on. The check engine light will be on and will then go off and then on again according to the codes the engine controler happens to have in it. If the check engine light was on when you stopped the car, then there is at least one code in the controler. The light will blink the codes like this.
Cycle the key three times and leave on on the third time. light on for about 3-4 seconds then goes out for about 2 seconds and then blinks one time and goes out for 3 seconds this is for the no.1. Then the light blinks 3 times and goes out for about 3-4 seconds. You have the code 13. You could have a whole string of codes in the controler memory. It could be something like this. key cycled 3 times, light on for 3-4 seconds, then blinks 1 time, pause, 3 times, longer pause, 2 times ,pause 4 times, longer pause, then 5 times, pause 5 times the goes out.
This is code ; 13,24, 55. code 55 isn't really a code. It just tells you it's the end of any codes the controller has.
If you disconnect the battery and hook it back, you will have code 13 which simply mean 'battery disconnect'. It will errace it's self after several starts if it's not disconnected again. If you cycle the key and you get 55, this means there are no codes recorded at this time.
You will allways get 55 when checking for codes wheather there are fault codes or not. The light on for a few second before the codes start flashing is only a bulb check. Some codes like 13 will not turn the check engine on, but but will leave a code for diagnostic purposes only. If you have the check engine light on and accellerate and the light begains to blink, then the controller is telling you that you have an engine miss and are running the chance of burning out you're catalatic converter if you continue driving. Sometimes its advised to disconnect the battery after you have recorded the codes.
This will erase all codes that are present but were generated by conditions that aren't pertanent to the present condition. and then the codes that come back are the real ones to address.

Contains the entire list of Chrysler Engine Error Codes.

5-5 indicates no trouble codes available or recorded. There is no problems recorded in the computor.

• 11 No ignition reference signal detected during cranking (bad Hall effect) OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor. Can cause the engine to stop working entirely with no limp-home mode.

in order to get the trouble codes from your car you will need to either get an obd 1 reader from a local parts store or you can take it to any garage to have read.

did you know there was only 774 made in red? less made in white,, in 91,,keeper car!!

that said check for vacuum leak, could be a leak on intake

Small vacuum leak to start in evap system, which can quite often be traced back to gas cap. I'd clean gas cap seal good & add a little Vaseline, to the rubber "O" ring on cap, and wipe surface where cap screws in real good & clean, then have codes erased, or disconnect battery for a few seconds, and then see if it comes back. Make sure you put cap on tight after adding fuel.

Code 12 is battery disconnected lately. code 24 is faulty TPsensor. code 55 is end of message.
So, I'd replace my throttle position sensor.

I believe all the Mopar OBDC codes are the same. A list of the 2001 codes were posted on a PT Cruiser site here: 2001 Chrysler codes

Your error says the throttle position sensor and MAP sensor disagree with each other

I believe this is a warning of a transmission problem (flashing S4 light), and u should have it checked by a good trans. shop or dealer. When The engine light comes on and stays on,(does it only go on when the S4 light flashes?)it is a warning of a problem (fuel injection/emissions system), which u can check by doing the following: There is a Electronic Control Unit (ECU), located under the carpet on the passenger (front) side near where your feet would be. There is an LED display on the ECU, the display is a small circle, I believe located at the top center of the ECU. When u get the ECU exposed(by pulling back the carpet), turn the key on, and observe the LED. If any codes were stored regarding a problem, the LED will flash. Count the flashes, Codes 1 thru 9 are a series of short flashes, two digit codes use a long flash for the 1st digit, and a short flash for the 2nd digit. Codes are separted by a pause between displays. If u have multiple codes , they are transmitted in a alternating pattern. Time and space make it hassle to list all codes ( there are 19 for the 91 Prelude), so if u want to go ahead and check the codes, let me know what they are , and I'll tell u what they mean. Good Luck! countrycurt0
