P0213 Cold Start Injector 1

EmissionsRelevant
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. P0213 concerns cold start injector 1. 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
