P213D: EGR Throttle Control Circuit B High

P213D is the opposite electrical fault to P213C on EGR throttle B: the drive line carries voltage where the output stage expects ground, or the driver measures excessive current. A wire touching battery positive, a shorted motor winding that pulls too much current, or a mechanically blocked flap that overloads the motor are the usual triggers. The output stage switches off to protect itself, so the flap returns to its spring position and stops regulating. No manufacturer publishes thresholds for P213D; CARB requires output circuits to be checked for faults in both directions. Throttle A reports the same high condition as P2142, while P213A covers an open circuit and P213B a flap that moves but misses its target. Drivers notice the warning lamp, sometimes reduced power.

Medium severity. Can I keep driving?You can normally drive in moderation, but get it repaired soon: if the valve is stuck open, the engine may idle very poorly.

Symptoms

Check engine lamp on
Reduced power in some operating ranges
EGR readiness not completed

Most likely causes

Drive wire shorted to battery voltage
Shorted turns in the actuator motor causing overcurrent
Flap mechanically blocked, motor overloaded
Faulty output stage in the engine control module

What to check, in order

Start with the simplest. You can tick off each step.

Check the connector and any vacuum hoses
Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
Use live data to compare the commanded opening with the actual opening
Clean the valve and passages if they are clogged with carbon
Test the actuator with the scanner
Replace the valve if it still does not follow the command after cleaning

Good to know

Repair difficulty: medium
It can trigger limp mode.
It affects emissions.
