P2513 OBD-II Trouble Code: Event Data Recorder Request Circuit Low

diagnostic check engine light logo

P2513 code definition

The P2513 code relates to a fuel composition sensor circuit malfunction, most commonly stemming from an issue in the operation of the variable cam timing (VCT) solenoid, which changes the timing of the camshaft position to match engine speed and timing. By achieving the appropriate timing relationship, an engine can produce more horsepower through the larger movement of air in and out of the cylinders. There are two of these VCT solenoids in most modern engines, controlled separately by the engine control computer (ECC).

It may also be associated with other codes, such as: P0012, P0340, and P0345.

What the P2513 code means

P2513 is a OBD-II trouble code signalling an issue with the composition of fuel circulating through the engine, culminating in problems with the function of the VCT solenoid. When the VCT solenoid has an issue, the air and fuel mixture may not be in optimum proportions. This can result in contamination around the VCT solenoid valve, causing it to stick in either a closed or open position. This code will then trigger the illumination of the Check Engine Light to alert the driver of a problem requiring attention.

What causes the P2513 code?

The event data recorder request circulation low code may have these causes:

  • Broken oxygen sensor
  • Faulty VCT solenoid
  • Issue with the wiring harness near intake manifold bracket
  • Sticking VCT solenoid valve

What are the symptoms of the P2513 code?

The P2513 code causes the Check Engine Light to illuminate on the dashboard and can cause the following symptoms:

How may a technician diagnose the P2513 code?

In the hands of a trained technician, the P2513 code can be diagnosed on a vehicle using an advanced scan tool. This scan tool differs from those available at auto parts stores in that it has greater diagnostic capabilities for its factory sensor readings and is distributed solely to certified technicians. Such a qualified professional who has received training in how to use an advanced scan tool can then use it to amass and interpret an array of data to gain insight into what issue(s) caused the P2513 code to register.

In some cases, further testing may be necessary to determine the code’s cause, such as by clearing the code from the vehicle’s on-board computer and then driving the vehicle with the scan tool attached. This allows the technician to see if the issue was a one-time occurrence or an ongoing problem that requires attention.

At times, even further efforts are required to properly diagnose the cause of the P2513 code registering, including a more thorough inspection or use of other tools, such as:

  • Advanced scanner that can interpret data from the engine control module (ECM)
  • Digital voltage meter with attachments

Common mistakes when diagnosing the P2513 code

While installing a new VCT solenoid and valves may solve the issue that triggered the P2513 code to register, it may only serve as a short-term solution or fail to fix the problem at all. Oftentimes, an OBD-II trouble code like P2513 only indicates a symptom of a deeper issue or may have affected other systems on the vehicle. This is why it is crucial to have any vehicle registering a P2513 code inspected thoroughly by a trained technician in possession of specialized tools.

How serious is the P2513 code?

The P2513 fault code can potentially cause the following vehicle issues:

  • Damaged wiring harness by the intake manifold bracket
  • Faulty oxygen sensor
  • Faulty VCT solenoid
  • Sticking VCT solenoid valve

Through working with a qualified technician, the problem causing the fault code can be diagnosed with accuracy and consequently corrected. This repairs issues before they may affect other vehicle systems, necessitating more costly repairs down the road.

What repair can fix the P2513 code?

Commonly, the method a technician uses to repair the P2513 code is:

  • Confirm the validity of the P2513 code using an advanced scan tool.

  • Refer to factory repair manuals to determine the testing and values appropriate to the code.

  • Check for other OBD-II trouble codes to register, possibly indicating a larger associated issue.

  • When necessary, clear the P2513 code, test drive the vehicle with the scan tool attached, and watch for the same codes register again.

  • Connect a more advanced scan tool to interpret data from the engine control module (ECM)

  • Test drive the vehicle a second time with the advanced scanner attached, confirming the existence or return of the P2513 code.

  • Perform a thorough physical inspection of the VCT solenoid and related components.

  • Replace any part(s) that are found damaged.

Additional comments regarding the P2513 code

The process to diagnose the P2513 code is not necessarily a simple one and may take several hours for a qualified technician to determine the nature and severity of the problem. Since the improper function of the VCT solenoid may cause issues in other vehicle systems or parts, it is particularly important to seek attention from a professional trained and experienced in the use of technologically advanced diagnostic tools.
