How do I fix error P0203?

Possible fixes include:

  1. Replacement of the Cylinder 3 Fuel Injector.
  2. Repair or replacement of any wiring issues (damaged or broken wires)
  3. Fixing poor connections.
  4. Replacement of the PCM.

What does the code P0203 mean?

The P0203 is a diagnostic trouble code that is set when the engine control module (ECM) has detected a fault in the injector circuit for cylinder 3.

What causes a p0203 engine light code to appear?

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 First, using a DVOM check the resistance of the injector.

What does it mean when PCM says p0203?

Although generic, the specific repair steps may vary depending on make/model. P0203 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero.

Why is my spark plug not working in my car?

It depends on what specific trouble code is being stored. If it’s a specific cylinder it could be the spark plug wire (if your car has them) or a bad fuel injector (if you have individual injectors for each cylinder). It could also be low compression in that cylinder. If it’s the generic P0300 misfire code, that opens up more possibilities.

What kind of sensor is P0300 misfire code?

If it’s the generic P0300 misfire code, that opens up more possibilities. MAP sensor, EGR system, restricted exhaust, low fuel pressure, oxygen sensors.

What does the error code mean on a spark plug?

The error code refers to a specific cylinder misfire, which means it needs a more thorough diagnosis. For a cylinder misfire, you have to change faulty components, such as coils and spark plugs. This is to isolate the exact cause of the misfire.

What are the causes of a p0302 misfire?

For a P0302 code, the causes could be: 1 Cylinder #2 Spark Plug 2 Cylinder #2 Coil 3 Cylinder #2 Wiring 4 Cylinder #2 Fuel Injector

What does the error code p0303 mean on a car?
