P213B — Exhaust Gas Recirculation Throttle Control Circuit "B" Range/Performance

P213B — Exhaust Gas Recirculation Throttle Control Circuit "B" Range/Performance. A fault in the exhaust gas recirculation (EGR) system. The car is usually drivable while you plan the repair. Typical causes: carbon buildup blocking the EGR valve or passages, vacuum leaks in EGR control lines, faulty EGR solenoid or wiring.

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 P213B 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 Compare the exhaust gas recirculation throttle control circuit "B" live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Subsystem check Command the EGR valve open/closed with a scanner and watch idle quality and position feedback.
  6. Subsystem check Remove and inspect the EGR valve and passages for carbon blockage before replacing parts.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P213B does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P213B (parts and labor, USD, independent shop rates): Repair vacuum lines or wiring: $80–$250; Replace the EGR valve: $250–$650; Clean the EGR valve and passages: $120–$350. Overall, fixing P213B 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

Is it safe to drive with P213B?

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 much does it cost to fix P213B?

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

How do I diagnose P213B myself?

Start with a scan: confirm P213B, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the exhaust gas recirculation throttle control circuit "B", and verify the suspect component against live data before buying parts.

What are the symptoms of P213B?

Drivers most often notice: hesitation and pinging under load, rough idle or stalling at idle, slight power loss, increased NOx emissions.

Will P213B clear itself?

Sometimes P213B 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 P213B mean?

When P213B 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" range/performance. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

“Range/performance” means the signal from the exhaust gas recirculation throttle control circuit "B" is electrically valid but does not match what the module expects for current operating conditions. The wiring is usually intact; the problem is a degraded component, a drifted sensor or a mechanical fault upstream.

To set P213B, the control module compares live readings of the exhaust gas recirculation (EGR) system against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

Common symptoms of P213B

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

What causes P213B?

  • mechanical fault that the sensor correctly reports
  • degraded or drifting exhaust gas recirculation throttle control circuit "B"
  • incorrect calibration after a module update or battery disconnect
  • faulty EGR solenoid or wiring
  • failed EGR valve or position sensor
  • carbon buildup blocking the EGR valve or passages
  • vacuum leaks in EGR control lines
  • ECM control circuit fault

How to diagnose P213B

  1. Connect an OBD2 scanner, confirm P213B is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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. Visually inspect the wiring harness and connectors related to the exhaust gas recirculation (EGR) system for damage, corrosion, chafing or poor contact.
  4. Compare the exhaust gas recirculation throttle control circuit "B" live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Command the EGR valve open/closed with a scanner and watch idle quality and position feedback.
  6. Remove and inspect the EGR valve and passages for carbon blockage before replacing parts.
