What does trouble code p0204 mean on cylinder 4?
This code means the PCM (powertrain control module, also known as ECM or engine control module in other makes) detects a problem in the injector or its wiring, or in the injector circuit for cylinder 4. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II, or vehicles made in 1996 to present.
Why is my PCM setting error code p0204?
If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 4, which activates the Error Code P0204. The PCM also works by monitoring the resistance circuit, and sets the code if it’s too high or too low.
What does p0304 mean on a spark plug?
If your vehicle is equipped with individual coil packs instead of spark plug wires, start by removing the cylinder 4 coil and swapping it with the cylinder number 1 coil. If the misfire moved to cylinder number 1 (P0301), then you have determined that the coil pack is faulty and needs replacement.
What is the error code for cylinder 4 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 4, which activates the Error Code P0204.

What causes the cylinder 2 injector to malfunction?
The most common causes for this code include: 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
What does the p0200 code on a fuel injector mean?
What the P0200 code means. P0200 means that the engine control module (ECM) has detected a malfunction in the fuel injector circuit.
What is the OBD-2 trouble code for injector?
P0200 is a generic OBD-II diagnostic trouble code in reference with the injector circuit Note: This code is similar to P0201, P0202, P0203, P0204, P0205, P0206, P0207, and P0208. And may be seen in conjunction to engine misfire codes, or engine lean and rich condition codes.
What is the code for cylinder 4 injector circuit?
P0204 tells technicians a malfunction was found for cylinder 4 injector circuit. This code is similar to P0200 – P0203, and P0205 – P02012.
