What does a cylinder 3 misfire code mean?
P0303 | Cylinder 3 Misfire Detected | When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary,
What is the error code for cylinder 3 injector?
When the injector is switched off, the PCM expects to see a voltage close to battery voltage or “high”. 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.
What does the p0303 code on a Chrysler cylinder mean?
The P0303 code means that the cylinder 3 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 3. If the problem persists more tests needs to be done to diagnose problem, see “Possible Causes”.
How does the ECM detect a cylinder misfire?
By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM can detect individual cylinder misfire events. Extreme cylinder misfire events can cause catalytic converter damage. The malfunction indicator lamp (MIL) will flash when the conditions for catalytic converter damage are present.

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.
Can a fuel injector fault be set during a misfire?
In Spark Ignition Direct Injection (SIDI) system applications, if a fuel injector fault DTC is set during a misfire event, the ECM will not re-enable the injector. Need more information on how to fix the P0303 code?
