P0214 Cold Start Injector 2

Drive cycleNot required
Limp modeNo

A cold start injector is an additional injector in the intake manifold that sprays extra fuel for a few seconds while a cold engine is cranked. In classic Bosch systems a thermo-time switch on the block powers it directly, without the engine module – such systems cannot set a code at all. A code is only possible where the engine module drives the valve and monitors its circuit, as CARB requires for output components. From the 1990s the main injectors took over cold-start enrichment, so the code only fits early OBD II engines. P0214 concerns cold start injector 2, for example on a second intake bank. No manufacturer using it was found in GM, Ford or Saab documents.

Likely causes

Connector or wire corroded or open
Valve coil open or valve stuck
Thermo-time switch or control relay faulty
Driver stage in the engine module faulty

Symptoms

  • Check engine light on
  • Poor cold start, long cranking in cold weather
  • Leaking valve: hot-start problems, flooding, black smoke
