P213A — Exhaust Gas Recirculation Throttle Control Circuit "B" /Open

OBD2 code P213A flags a problem with the exhaust gas recirculation (EGR) system (exhaust gas recirculation throttle control circuit "B" /open). The car is usually drivable while you plan the repair. Common culprits: carbon buildup blocking the EGR valve or passages, vacuum leaks in EGR control lines, failed EGR valve or position sensor.

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK Generally safe to drive in the short term. Expect rough idle, pinging and higher emissions; on some cars the engine may derate. If the engine stalls or runs very rough, treat it as urgent.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P213A is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the exhaust gas recirculation (EGR) system for damage, corrosion, chafing or poor contact.
  4. Subsystem check Command the EGR valve open/closed with a scanner and watch idle quality and position feedback.
  5. Subsystem check Remove and inspect the EGR valve and passages for carbon blockage before replacing parts.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P213A does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P213A (parts and labor, USD, independent shop rates): Replace the EGR valve: $250–$650; Clean the EGR valve and passages: $120–$350; Repair vacuum lines or wiring: $80–$250. Overall, fixing P213A usually costs between $80 and $650. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What are the symptoms of P213A?

Drivers most often notice: slight power loss, increased NOx emissions, Check Engine Light on, rough idle or stalling at idle.

How much does it cost to fix P213A?

Replace the EGR valve — $250–$650; Clean the EGR valve and passages — $120–$350; Repair vacuum lines or wiring — $80–$250. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P213A mean?

OBD2 code P213A flags a problem with the exhaust gas recirculation (EGR) system (exhaust gas recirculation throttle control circuit "B" /open). The car is usually drivable while you plan the repair. Common culprits: carbon buildup blocking the EGR valve or passages, vacuum leaks in EGR control lines, failed EGR valve or position sensor.

What is the most common cause of P213A?

The most common causes are: carbon buildup blocking the EGR valve or passages, vacuum leaks in EGR control lines, failed EGR valve or position sensor.

Will P213A clear itself?

Sometimes P213A clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does P213A mean?

When P213A appears on a scan, it means the control module has flagged a problem in the exhaust gas recirculation (EGR) system: exhaust gas recirculation throttle control circuit "B" /open. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P213A — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes P213A?

  • faulty EGR solenoid or wiring
  • ECM control circuit fault
  • carbon buildup blocking the EGR valve or passages
  • failed EGR valve or position sensor

Common symptoms of P213A

  • slight power loss
  • increased NOx emissions
  • Check Engine Light on
  • rough idle or stalling at idle
  • hesitation and pinging under load

How to fix P213A

Start with the cheapest and most common causes before replacing expensive parts:

  • Replace the EGR valve — $250–$650
  • Clean the EGR valve and passages — $120–$350
  • Repair vacuum lines or wiring — $80–$250

Can you drive with P213A?

Generally safe to drive in the short term. Expect rough idle, pinging and higher emissions; on some cars the engine may derate. If the engine stalls or runs very rough, treat it as urgent.
