P2607: Intake Air Heater B Circuit Low

Standardized SAE J2012 code · P26xx — Computer and output circuits

What does P2607 mean?

Voltage on the secondary intake air heater control line is below the expected window. Usually a short to ground or a shorted relay coil.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Common causes

  • High Control wire shorted to ground
  • Medium Internal short in relay coil
  • Low Connector pins corroded - high contact resistance

Likelihood is a general estimate across vehicles; your make and model may differ.
