P213A EGR Throttle Control Circuit B/Open

Drive cycleNot required
Limp modePossible

P213A concerns the electrical drive of EGR throttle B, a second motor-driven regulating flap found on some diesel layouts. Such a flap closes partly so that pressure ahead of the intake falls below exhaust pressure and enough exhaust gas can be recirculated; it also cuts air at engine stop. The engine module watches the output stage of flap B and stores P213A when the circuit is open or the driver flags a fault it cannot assign to low or high. No manufacturer documents this code publicly, so thresholds are unknown; CARB treats the flap as an output component whose circuit must be monitored. Flap A reports the same fault as P0487. Expect the flap to rest in its spring position, reduced EGR and possibly a power limit.

Likely causes

Loose, corroded or broken connector or wire at throttle B
Open winding in the throttle B actuator motor
Harness damaged by heat near the exhaust or EGR cooler
Faulty output stage in the engine control module

Symptoms

  • Check engine lamp on
  • Reduced power or limp mode
  • Engine shudder when switched off
  • EGR readiness not completed
