P0260 Injection Pump Fuel Metering Control “B” High (Cam/Rotor/Injector)

If you’re a car owner, you’re probably familiar with the check engine light. It’s the light on your dashboard that tells you something isn’t quite right with your vehicle.

One of the most common codes that can trigger the check engine light is P0260, Injection Pump Fuel Metering Control “B” High (Cam/Rotor/Injector). In this article, we’ll dive into what this code means, what causes it, and what you can do to fix it.

What is P0260?

P0260 is a diagnostic trouble code (DTC) that indicates a problem with the injection pump fuel metering control “B” circuit. Specifically, it means that the fuel injector on cylinder number two is receiving too much fuel, causing the fuel system to run rich. This can lead to a variety of issues, including decreased fuel efficiency, rough running, and engine damage if left unaddressed.

What Causes P0260?

There are several potential causes of P0260, including:

  1. Faulty Injector: The fuel injector on cylinder number two may be faulty, causing it to receive too much fuel.

  2. Wiring Issues: There may be a problem with the wiring or connections in the injection pump fuel metering control “B” circuit.

  3. Injector Control Module (ICM): The ICM, which controls the fuel injectors, may be malfunctioning.

  4. Bad PCM: The Powertrain Control Module (PCM), which is responsible for managing the engine’s fuel and ignition systems, may be faulty.

  5. Fuel Pressure Issues: If the fuel pressure is too high, it can cause the fuel injector to receive too much fuel.

  6. Clogged Fuel Injector: A clogged fuel injector can cause the fuel system to run rich, leading to P0260.

How to Fix P0260

The first step in fixing P0260 is to diagnose the underlying cause of the issue. This typically involves using a scan tool to read the diagnostic trouble codes stored in the vehicle’s computer. Once you’ve confirmed that the code is indeed P0260, you can begin troubleshooting the issue.

Here are a few potential fixes for P0260:

  1. Replace the Fuel Injector: If the fuel injector on cylinder number two is faulty, you’ll need to replace it.

  2. Repair Wiring Issues: If there are any issues with the wiring or connections in the injection pump fuel metering control “B” circuit, you’ll need to repair them.

  3. Replace the ICM: If the ICM is malfunctioning, you’ll need to replace it.

  4. Replace the PCM: If the PCM is faulty, you’ll need to replace it.

  5. Check Fuel Pressure: You’ll need to check the fuel pressure to ensure that it’s within the manufacturer’s specifications. If it’s too high, you’ll need to address the underlying issue.

  6. Clean or Replace Clogged Fuel Injector: If the fuel injector is clogged, you’ll need to either clean it or replace it.

Conclusion

P0260 is a common code that can trigger the check engine light. It indicates a problem with the injection pump fuel metering control “B” circuit, specifically that the fuel injector on cylinder number two is receiving too much fuel. There are several potential causes of P0260, including a faulty injector, wiring issues, a malfunctioning ICM, a bad PCM, fuel pressure issues, and a clogged fuel injector. To fix P0260, you’ll need to diagnose the underlying cause of the issue and address it accordingly.

FAQs:
