What is the error code for cylinder 2 injector?
Corroded fuel injector, connections or wiring Poor or broken electrical connections in the connector or harness Open or short wiring harness for the cylinder 2 injector circuit Defective fuel injector power circuits As with most error codes, qualified mechanics check this error code by hooking it up to advanced scanner and check for the codes.
Why is there an error code p0203 on cylinder 3?
If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 3, which activates the Error Code P0203. The PCM also works by monitoring the resistance circuit, and sets the code if it’s too high or too low.
What should I do if my Mercedes injector is not working?
Once identified the work can begin – Run the engine until nice and warm then turn it off and remove the keys. Remove the turbo supply hose to the inlet manifold and split the composite intake manifold by removing the pins that secure it to the lower section.
What is the code for cylinder 3 malfunction?
This code is very similar to P0200, P0201, P0202, P0204, P0205, P0206, P0207, and P0208. Additionally, this code can be seen in engine misfire, rich and lean conditions.
What causes the number 3 cylinder injector to short?
The number three cylinder injector circuit has a short somewhere in the circuit from the ECM to the injector. This includes the wiring and connections. The number three injector is shorted electrically internally causing the circuit high current condition.
What causes DTC on number one fuel injector?
Possible causes for this DTC include: Dirty fuel injector supplying the number one cylinder. Faulty fuel injector. Plugged fuel injector. Open or short in the fuel injector harness. Loose or corroded fuel injector connector.
What happens when a fuel injector is malfunctioning?
In short, this fuel injector is malfunctioning for one of a variety of reasons. It is important to diagnose and repair this type of problem as soon as possible. When a fuel injector malfunctions, it causes ripples down the line, meaning the engine’s operating parameters change due to the mixed signals at the PCM.
Once identified the work can begin – Run the engine until nice and warm then turn it off and remove the keys. Remove the turbo supply hose to the inlet manifold and split the composite intake manifold by removing the pins that secure it to the lower section.
