91 3.1 car starts and runs fora minute then dies code 43 came up( fixed wire kn Sen.) now 21and 43 came up?


You didn't say what the make and model are, but if code 43 is a knock sensor issue I guess its a GM product.
Code 21 means the TPS voltage was too high, and code 43 means the knock sensor voltage was too high or too low.
Neither code would kill the engine. Just turn the warning light on.
If the throttle position sensor failed, you would get the effect of stalling on acceleration.
You may need to narrow down the possible causes to spark or fuel, and in the end it could be the engine computer. It could also be a relay or other electrical component.

I have a Saab with a service code P0304 I looked into it usually bad ignition coil...I replaced the coil but No go, any ideas?


P0304 code means - Cylinder 4 Misfire detected.

Possible causes are:

- Faulty spark plug 4
- Clogged or faulty fuel injector 4
- Faulty ignition coil 4
- Fuel injector 4 harness is open or shorted
- Fuel injector 4 circuit poor electrical connection
- Ignition coil 4 harness is open or shorted
- Ignition coil 4 circuit poor electrical connection
- Insufficient cylinder 4 compression
- Incorrect fuel pressure
- Intake air leak

I need to know what the code for a 1993 honda accord it flashed 4 slow then three short fast flashes, my car has been lagging really bad and i dont know exactly what i need to do to fix it i was told it is...


Found this for you on the web. Good luck.

What is code 43?

Code 43 is "fuel supply system."

This code will trip when the ECU and the readings from the o2 sensor don't get along(in layman's term or easy enough for Si Speed to understand biggrin.gif) read the above two threads).

How to diagnose and fix?

First things first, when was the last time you changed your O2 sensor? Start by replacing that first because most likely, that's the main culprit. Now, you may wonder why doesn't the CEL indicate code 41(heated o2 sensor)? Usually when the o2 sensor is completely dead, that code will trip. Also, even though the o2 sensor is working, the voltage or ground isn't 100% Because of that, it will correlate with code 43.

If replacing the o2 sensor did not help code 43 to disappear, next thing is to replace your fuel filter. A clogged fuel filter will also trip code 43.

Next up, did you install an aftermarket Fuel Pressure Regulator? I have a few friends with 3rd gen Preludes and both of them installed aftermarket FPR's and they too, trip code 43. Him and a lot of people who install aftermarket FPR's mess with the PSI and that will cause code 43 to appear(on a stock ECU mind you). Bring it back to stock PSI to help fight code 43.

Those are the 3 main culprits that will cause code 43 from my experiences. Injectors, spark plugs & wires, most likely anything "fuel' related that isn't working properly will also cause code 43.

1997 concorde. Turned ignition on/off/on/off/on and received code: 1-2-5-4-5-5 I can not find this code online. Driving down the road it just quit running.


You have three codes there
12 - Memory standby power recently lost (Recently disconnected the battery, always appears this code (not problem))
Power loss light: Off
Limp-in mode: None

54 - No fuel injector sync pickup signal during engine rotation
Power loss light: On
Limp-in mode: Logic module will guess at injector timing

Possible Causes
Bad connection or wiring - Check the wiring and connections between the hall effect sensor (located underneath the distributer cap) and the logic module. Check the continuity of the two 3 conductor cables coming out of the sensor--these are prone to fatiguing and breaking inside the insulation where they exit the sensor if the cables are not properly tied down. You may be able to resolder them. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Hall effect sensor failure - Check the two, flat 3 conductor cables coming out of the sensor. These often fatigue where they exit from the sensor. Upon replacing the sensor, make sure the cables are clipped or tied to the distributor cap shroud (or elsewhere) so they do not swing around.

Diagnostic Method - Trigger Parameters
- Engine cranking or running (signal coming from ignition reference sensor)
- No signal from the fuel injector sync pickup sensor

Results If Component Fails: Fault code 54 is stored. The engine will stall and will not start.

55 - End of message (Test Finished)
Power loss light: Off
Limp-in mode: None

Hope this helps (remember to rate this answeerr).
