If the injector is fine, the P0203 OBD2 code is most likely caused by
faulty wiring or poor electrical connection
. The fuel injector utilizes power to deliver the fuel. Any wiring problems will cause the injector to operate poorly, hence affecting engine performance.
What does fault code P0203 mean?
What the P0203 code means. 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
. … Once the DTC is set, the car will enable a failsafe mode which prevents further damage to the vehicle.

The
Reductant Level Sensor
tells the engine computer (PCM) how much DEF is left in the tank. If the PCM sees that the DEF level is too low, code P203F is set. Additional warnings may be present on the instrument cluster. Failure to add DEF fluid may result in the engine not restarting until more DEF fluid is added.

How much does it cost to fix injector circuit malfunction?
This is going to depend on where the issue is: Faulty injectors – This will cost
between $1,000 and $1,500
if you take it to a shop. If you do the work yourself, it will cost you around $800-$1,000 for the injector parts.

So, the most common cause of leaky injectors is;
the failure of the O-ring, where the injector meets the fuel rail
. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
Is there a code for fuel injector?
P0253 Code
