P0203 corsa


you may have bad fuel in the vehicle..I would put fresh fuel in the vehicle and add some octane booster to the fuel also with a bit of injector cleaner..then get all the codes removed..

Have a 2005 f-150 5.4.having trouble with codes. p0053,p0203,p0303 and pO453. Where to start and can u fix one thing to cancel out 2 or more codes.


code p0053 refers to heated oxygen sensor (HOS) bank 1-circiut malfunction===causes --wiring --- HO2S
code p0203 refers to injector 3 circuit malfunction==causes---wiring--injector ---ECM
code p03030refers to cylinder 3-- misfire detected===causes--engine mechanical fault--wiring---ignition/ fuel system---injector---ECT/MAF sensor---ECM
code p0453 refers to Evaporative emissions(EVAP) pressure sensor--high input==causes---wiring short to positive--EVAP sensor---ECM
code po203 and po303 both have injector as possible fault but the others you will have to fix separately. I doubt an ECM fault as there would be more problems evident so check that one last as it big dollars.

Po 203


P0203 - Injector Circuit Malfunction Cylinder 3
Possible causes- Fuel Injector 3 harness is open or shorted
- Fuel injector 3 circuit poor electrical connection

- Faulty fuel injector
- Faulty Engine Control Module (ECM) When is the code detected?The P0203 is set if the Engine Control Module (ECM) detects a low or high voltage drop or resistance at the number 3 engine cylinder injector.

P0203 only when the engine is hot


The causes of a P0203 engine light code could be any of the following:
* Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
* Open in the wiring to the injector
* Short in the wiring to the injector
* Bad PCM

Check and test this possible solutions:
  1. First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
  2. Check for voltage at the fuel injector connector. It should have 10 volts or more.
  3. Visually check the connector for damage or broken wires.
  4. Visually check the injector for damage.
  5. If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
  6. At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
  7. Replace the injector
Hope helps.

P0203 - Injector Circuit Malfunction Cylinder 3

Powertrain Control Module (PCM) or Electronic Control Module (ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The PCM/ECM will trigger the P0203 code when the resistance or voltage drop at the injector #3 is out of specifications.

Causes:
- Open or shorted wiring harness to the injector #3
- Bad injector #3
- Bad PCM/ECM

Solutions:
- If damage, repair injector wire harness or connector
- Replace injector
- Replace PCM or ECM


P0204 - Injector Circuit Malfunction Cylinder 4

Same info as the P0203 DTC


P0300 - Random/Multiple Cylinder Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

Causes:
- Improper spark plug
- Insufficient compression
- Incorrect fuel pressure
- The injector circuit is open or shorted
- Fuel injectors may be faulty
- Intake air leak
- The ignition signal circuit is open or shorted

Solutions:
- Perform Injector Service
- Replace Spark Plugs
- Replace Injectors
- Replace Ignition Coils

I am getting error code P0203 on my 2000 Hyundai Sonata, V6. This indicates #3 Fuel injector open circuit. Have replaced fuel injector and continuity of wiring is strong. I am stumped as I continue to get...


Ok.... let's get this clear -- you have 'VERIFIED' no problem with the wiring between the injector connector pins and the ECM?? and you have good pin tension at the injector? and good pin tension at the ECM? and good continuity between the injector & the injector fuse? If in fact this is SO, you have a bad ECM (Engine Control Module). 303f9ab.jpg
