What is OBD-II Code P2A1C – Injection Pump Fuel Metering Control E Low (Cam/Rotor/Injector)



An OBD-II code is a unique diagnostic trouble code produced by onboard diagnostics systems in vehicles produced after 1996. OBD codes provide drivers with information about problems occurring within their cars, and they can help mechanics pinpoint problems faster, reducing repair time. One of the OBD-II codes that a driver may encounter is P2A1C – Injection Pump Fuel Metering Control E Low (Cam/Rotor/Injector). In this article, we will explain what this code means, causes, symptoms, and how to repair the issue.

Causes of P2A1C OBD-II Code

P2A1C OBD-II Code refers to a malfunction in the fuel injection system, specifically with the fuel metering control E. Some of the factors that cause this error code include damaged injectors, problems with rotor wear and tear, and damaged camshaft lobe.

Symptoms of P2A1C OBD-II Code

When the P2A1C error code appears, the engine control module (ECM) will turn on the Check Engine Light. Other symptoms of this error code include the engine running poorly, difficulty starting the engine, reduced fuel efficiency, and a rough idle.

Repairing P2A1C OBD-II Code

If you have encountered the P2A1C code, you should take your car to a trusted mechanic for diagnosis. Here is a step-by-step guide on how to repair the P2A1C code:

1. Inspect the Fuel Pump

The fuel pump’s job is to deliver fuel to the engine and maintain the correct pressure level. A damaged or malfunctioning fuel pump can cause the injection pump fuel metering control E to run low, resulting in the P2A1C code. In this case, a mechanic will inspect the fuel pump and replace it if it has any issues.

2. Inspect the Injectors

Fuel injectors are responsible for injecting fuel into the engine’s combustion chamber. If these injectors are blocked or damaged, they may not be delivering the correct amount of fuel, resulting in the P2A1C code. An inspection of these injectors by a mechanic can identify any problem, and the replacement of damaged fuel injectors will resolve the issue.

3. Inspect the Camshaft

Another cause of the P2A1C code is the wear and tear of the camshaft. This damage can affect the correct operation of the fuel metering control E, which may result in low fuel injection. If the camshaft is worn or damaged, a mechanic can replace it to fix the issue.

4. Inspect the Rotor

The rotor is part of the fuel injection system responsible for channeling fuel to the right cylinders. Wear and tear can cause it to malfunction, resulting in the P2A1C error code. If the rotor is damaged, replacing it can be the solution to repairing the P2A1C code.

5. Inspect the Fuel Line

A problem with the fuel lines can cause the fuel metering control E to run low, resulting in the P2A1C code. A mechanic can inspect the fuel line to identify any leaks or damage and replace it if necessary.
