What Does P213D Mean?
The PCM detects abnormally high voltage in the EGR throttle control circuit B. This suggests an open circuit, short to voltage, or sensor providing excessive voltage signal.
Common Causes
30%
Open circuit in EGR position sensor wiring
25%
Short to voltage in EGR control circuit
25%
Failed EGR position sensor reading high
12%
Poor ground connection for EGR system
8%
PCM internal fault in EGR control circuit
Diagnostic Steps
1
Step 1: Measure voltage at EGR position sensor with ignition on and compare to specifications
2
Step 2: Check for open circuits by testing continuity from sensor to PCM with ignition off
3
Step 3: Inspect connectors for pushed-out pins or corrosion causing open circuits
4
Step 4: Test for shorts to battery voltage using a multimeter on signal wires
5
Step 5: Verify proper ground circuit continuity and resistance
Estimated Repair Cost
$120 - $550
Parts + labor, varies by vehicle and location
The PCM detects abnormally high voltage in the EGR throttle control circuit B. This suggests an open circuit, short to voltage, or sensor providing excessive voltage signal.
The most common cause of P213D (Exhaust Gas Recirculation Throttle Control Circuit "B" High) is: Open circuit in EGR position sensor wiring
Typical repair costs for P213D range from $120 to $550, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but performance may be affected. Increased NOx emissions and potential for engine knock under load.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P213D to identify the root cause.
