P0214 - P0214 Usually Means Injector Circuit Malfunction for Cylinder 14

P0214 is a generic OBD-II injector circuit code for cylinder 14.

This is a generic OBD-II guide that can apply across many makes. Exact test flow, sensor locations, and repeat failure patterns can still vary by manufacturer and engine family.

Severity

High

Keep driving?

Depends - see below

Most likely cause

A connector issue, wiring fault, or failed injector is usually the first place to look.

DIY friendly?

First checks yes

First checks take 10 to 20 minutes for the first checks. No special tools are usually needed for the first checks.

Can you keep driving?

Can you keep driving?

Stop driving if any of these apply

  • !The check-engine light is flashing.
  • !The engine is shaking badly, stalling, or struggling to accelerate.
If the light is steady and the vehicle still drives normally: Maybe, but only for a very short distance if the engine still runs smoothly.

What to check first

Step-by-step checks

  1. 1

    Free - no tools

    Inspect the injector connector and harness for looseness, corrosion, or heat damage

  2. 2

    Free - no tools

    Check for recently disturbed work around the fuel rail or injector area

  3. 3

    Basic tool needed

    Use scan data to see whether the fault stays with cylinder 14 or moves when parts are swapped

  4. 4

    Basic tool needed

    Look for rough running or a fuel smell that might point toward the injector side of the diagnosis

  5. 5

    Basic tool needed

    Keep clear of hot exhaust parts while checking the injector area

If the code returns

  • -If the fault moves with the injector, replacement becomes more likely than harness repair.
  • -If the code comes back after connector work, revisit the driver circuit and continuity checks.
  • -If the cylinder still misfires after injector checks, test compression and ignition next.

Background

What this code means

P0214 is a generic OBD-II injector circuit code for cylinder 14.

A fault on cylinder 14 can come from the injector, the harness, the connector, or the ECU driver side of the circuit.

A cylinder-specific misfire, rough idle, or one-cylinder imbalance can fit this code.

Diagnosis

Common causes

Most common

Injector circuit wiring fault

A damaged wire can prevent cylinder 14 from firing correctly.

Common

Loose or corroded connector

A poor connection can make the fault intermittent.

Common

Failed injector

The injector may be electrically open or stuck.

Possible

Driver circuit issue

The ECU output may not be commanding the injector normally.

Avoid these mistakes

What not to do

  • xDo not keep driving if the engine is shaking badly or the check-engine light is flashing.
  • xDo not replace injector or solenoid parts before checking the connector, wiring, and fuel supply side.

Parts

Parts that may need replacing

PartTypical costNotes
Fuel injector$80-$300Relevant when the injector itself is confirmed bad.
Connector pigtail repair$15-$90Worth checking if the plug or pins are damaged.
Injector wiring repair$20-$160Useful if the harness has an open, short, or heat damage.

Source notes

Generic OBD-II (SAE J1979 / ISO 15031-5). P0214 was expanded around common injector circuit faults, including wiring issues, connector problems, and injector failure.

This guide is written as a generic multi-make reference, so bulletin history, sensor locations, and repair order can still change by manufacturer and engine family.

This is generic OBD-II guidance and should not override vehicle-specific service information. Exact diagnosis and repair steps vary by make, engine family, and model year.
