My 1989 legacy will start, idle but it wont run properly. There are no fault codes coming up on dash. Is it the water temperature sensor?

Hi this sounds like the throttle position sensor as these dont trigger an error code or engine light when they start to go, anything else like fuel pump or knock/cam sensors or relay will. secondly it could be a coil pack causing it to miss/**** quite a bit

There are several possibilities for this problem. A "cold start" sequence is suppose to activate based on water temperature and the signal from the water temperature sensor. This makes the fuel rich and adjusts timing to make the engine run better when cold. It works like a choke only it is electronic.

There may be 2 sensors with one making the dash gauges work and the other doing the engine controls. If not 2, then 1 sensor would do the whole job.

Another possibility is an air leak in the fuel system which makes the system bleed dry overnight. It is far less common on gas engines but happens a lot on diesels.

Some earlier Ford engines from 1984 to I don't know when they stopped on trucks, would use a step-up solenoid on the accelerator bracket that worked off water temperature. Sometimes a bad water thermostat would make the temperature controls malfunction the other way (High idle, clicking, low idle) that would stall and engine as the temperature vary.

this is all controlled by the CPU as it gets messages from the sensors. If it needs attention it is because some sensors are not working properly. Run fault codes to find out what is wrong.

I own a 1997 subaru legacy gt car wont start, turns over but wont start was running okay before this happened


Hello


The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Mil on fault code p2188 help please


2188 rich at idle,Ive seen the injector creat this fault by not having the ability to atomize fuel properly are you willy to put a bottle of fuel injector cleaner in the fuel tank. This vehicle is equipt with a air ratio when it fails system goes lean, try this first but dont wait too long rich condition can destroy the catalytic convertor

I need to know what the following codes mean for a 1989 Dodge Ram. 12 24 35 52 17


12 Battery or computer recently disconnected (will occur on most cars most of the time, it indicates a low / missing battery happened in the last 50 key starts. Don't worry about it. — Tom Wand)

24* Throttle position sensor over 4.96V (SEE NOTE #3)

35 Cooling fan relay circuit open or shorted

52 Oxygen sensor stuck at rich position (SEE NOTE #5!)
OR
52 Internal logic module fault ('84 turbo only)

17 Engine stays cool too long (bad thermostat or coolant sensor?)

NOTE 3
Matt Rowe: “The throttle postion circuit tells the computer how far the accelerator is depressed. The Throttle Position Sensor (TPS) is on the throttle body on the opposite side of the throttle cable. The connector should have a round rubber cover over the connections. Clear the fault codes, start the car and try jiggling the wires/connectors to try to trip a fault code. Loss of this signal could cause other problems.”
Tom Wand: “Throttle Position Sensors (TPS) will on some early 1990s trucks start to drift high in voltage, there was a problem with these and the idle will not set low enough. Need to replace if it does this. As I recall, the output voltage at idle is 2.4 volts, much above is no good.”

NOTE 5
Wade Goldman wrote: In my case, the breather tube leading into the catalytic converter had rusted and become detached. This some how would cause the sensor to read an over rich condition and run crummy. I did not trust the reliability of the weld over a corroded surface and opted for the more expensive route of replacing the converter, breather tube and all.

More details can find in 80s-codes

Hope thats help (remember rated this FREE help) Good luck.

check the IACV (idle air conrol valve) which monitors idle speed. a clean out of one is a good idea periodically either way.

I would not recommend just resetting the light unless you have corrected the reason it was on…..Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on. I have seen the computer make the fan run all the time when it sees a problem with the coolant temp sensor.
