P0214 — Cold Start Injector 2

Generic OBD-II · all makesPowertrain (engine & transmission)

P0214 indicates a malfunction detected in the second cold start injector circuit responsible for enriching fuel during engine warm-up. This system is typically found on older vehicles and ensures stable combustion when the engine is cold. The control module has logged this code due to an electrical irregularity or performance issue within that specific injector path.

Symptoms

What causes it — most likely first

1. Failed cold start injector

Internal electrical failure or mechanical clogging prevents operation.

2. Open or shorted wiring harness

Damage to wires connecting the injector to the control module.

3. Corroded injector connector

Moisture or age causes poor electrical contact at the plug.

4. Faulty engine coolant temperature sensor

Incorrect data prevents the system from activating.

5. Fuel delivery pressure issues

Low pressure inhibits proper injector function.

6. Powertrain control module driver failure

Internal circuit board fault, statistically rare.

How it's diagnosed

  1. Visually inspect the injector wiring and connector for physical damage or corrosion.
  2. Measure the resistance of the cold start injector coil against manufacturer specifications.
  3. Check for proper voltage and ground signals at the injector harness during cranking.
  4. Verify engine coolant temperature sensor data matches actual engine temperature.
  5. Test fuel system pressure to rule out supply issues affecting injector performance.
  6. Inspect control module connectors and pins before considering module replacement.

Frequently asked

Does this code mean the engine computer needs replacement?

No, external components like the injector or wiring are the cause in most cases.

Can I drive the vehicle with this code present?

It may drive normally when warm, but cold starting performance will be compromised.

Will resetting the code fix the issue permanently?

No, the code will return if the underlying electrical or mechanical fault is not repaired.

Is this component common on modern vehicles?

No, this technology is primarily found on older model years and may require specialized sourcing.
