P0216 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.


To identify specific problems in the vehicle, a DTC code is an alphanumeric code applied to an OBD system. Specifically, the P0216 code is dedicated to a malfunction of the fuel injection timing control circuit.


The P0216 DTC code is triggered when your vehicle’s ECU identifies a defect in the fuel injection timing control circuit. This suggests that there is a timing issue affecting the fuel injection system.


The P0216 code may be activated for a number of reasons, such as:

  • Fuel injection pump malfunction or damage: This can cause the fuel injection timing control circuit to malfunction.
  • Wiring Problems: Correct timing control might be hampered by corroded or damaged fuel injection system wiring, connections, or harnesses.
  • ECM Issues: The code may appear if the engine control module is faulty and unable to correctly manage the timing of the fuel injection.
  • Fuel Delivery Issues: The timing of fuel injection might be thrown off by insufficient fuel pressure or fuel delivery problems.


The following symptoms may occur when the P0216 code is set off:

  • Engine Misfire: Uneven fuel injection timing might cause rough idling or frequent misfires.
  • Decreased Engine Performance: As a result of the timing issue, the engine’s power and acceleration were reduced.
  • A flashing check engine light: This is the most obvious sign that there is a problem with the fuel injection timing control circuit.


The following actions will be taken by a competent mechanic in order to diagnose the P0216 code:

  • OBD-II Scanner: The technician will use a diagnostic scanner to retrieve the stored trouble codes and freeze frame data for analysis.
  • Visual Inspection: A full visual inspection will be done to look for any fuel pump or visible electrical faults.
  • Fuel Pressure Test: Checking the fuel pressure might assist identify whether a lack of gasoline is the root cause of the error code.
  • Component Testing: To ensure correct operation, the fuel injection pump, fuel injection timing control circuit, and associated components will be examined.

Common mistakes

When dealing with the P0216 code, some common mistakes to avoid include:

  • Ignoring Other Codes: Sometimes, other related codes may be present, and ignoring them can lead to incomplete repairs.
  • Ignoring Visual examination: If you neglect visual examination, you can overlook obvious wiring or connection issues.
  • Not Checking Fuel Quality: Timing faults and fuel system problems might be exacerbated by low-quality gasoline.

How serious is this?

A considerable problem with the fuel injection timing control circuit of your vehicle is detected by the P0216 code. Failure to deal with this issue may lead to engine performance problems, limited fuel efficiency, or possible damage to the engines’ components. Therefore, the Code must be dealt with as a matter of urgency.

What repairs can fix the code?

repair manuals

There may be a need for the following fixes to fix the P0216 error code:

  • Fuel injection pumps that are malfunctioning must either be fixed or replaced.
  • Correcting Wiring Problems: Repair or replace faulty fuel injection system-related wiring, connections, or harnesses.
  • Replace the engine control module: If the ECM is broken, a replacement may be required.
  • Take Care of Fuel Delivery difficulties: Fix any fuel delivery difficulties, such as fuel pressure concerns, or make sure the fuel supply is clean.

Related codes

Codes that may be related to P0216 include:

  • P0217: Engine Overheating Condition
  • P0218: Transmission Over Temperature Condition


The DTC code P0216 is a sign of failure in the fuel injection timing controls, which may have significant effects on your vehicle’s performance. In order to keep your engine in optimal health and ensure an optimal driving experience, it is important that you get an accurate diagnosis and proper repairs as soon as possible. Call for professional help to resolve the problem as quickly and effectively as possible if you encounter a P0216 code or symptoms.
