What Does P213B Mean?
The PCM detects that the EGR throttle control circuit B is operating outside expected parameters during commanded operation. This indicates the EGR valve position or response does not match what the computer expects for the given conditions.
Common Causes
35%
EGR valve sticking or carbon buildup preventing proper movement
25%
Faulty EGR position sensor providing incorrect feedback
20%
Wiring issues in EGR control circuit including shorts or high resistance
12%
Vacuum leaks affecting EGR operation
8%
Failed PCM or internal circuit problem
Diagnostic Steps
1
Step 1: Visually inspect EGR valve and related wiring/connectors for damage or corrosion
2
Step 2: Use scan tool to monitor EGR position sensor data and command EGR valve operation
3
Step 3: Check voltage and resistance at EGR position sensor according to specifications
4
Step 4: Inspect EGR valve for carbon buildup and test vacuum supply if vacuum-operated
5
Step 5: Perform wiring continuity tests between EGR valve and PCM
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The PCM detects that the EGR throttle control circuit B is operating outside expected parameters during commanded operation. This indicates the EGR valve position or response does not match what the computer expects for the given conditions.
The most common cause of P213B (Exhaust Gas Recirculation Throttle Control Circuit "B" Range/Performance) is: EGR valve sticking or carbon buildup preventing proper movement
Typical repair costs for P213B range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive short distances. Reduced fuel economy and increased emissions may occur, and vehicle may fail emissions testing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P213B to identify the root cause.
