EGR Throttle Control Circuit B High

Brand: Generic
Type: P — Powertrain
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Open or shorted wiring on EGR/throttle position sensor circuit B
  • Poor or corroded connector or pin at the throttle/EGR actuator sensor
  • Short to battery voltage on the sensor signal
  • Faulty EGR throttle body or integrated position sensor (circuit B)
  • Intermittent ground or reference voltage problem
  • PCM input fault (rare)

Symptoms

  • MIL/Check Engine Light illuminated
  • Reduced engine power or 'limp' mode may activate
  • Poor idle, stalling, or drivability complaints under some conditions
  • EGR/throttle function abnormalities (hesitation or lack of response)

What to check

  • Read and record freeze frame data and all stored codes; note battery voltage
  • Scan live data: monitor EGR/throttle position sensor A and B PIDs simultaneously
  • Visual inspection of wiring harness and connectors at the throttle/EGR body for damage or corrosion
  • Backprobe the sensor connector and measure signal voltage with key on engine off and during operation
  • Check 5V reference and ground at the sensor connector
  • Wiggle test harness while observing live data for intermittent faults

Signal parameters

  • Reference voltage: approximately 5.0 V (check vehicle spec)
  • Expected sensor B signal: typically ~0.2–4.8 V across range; near low volts at closed and higher near open (vehicle-specific)
  • Short to battery will show near battery voltage (~12 V) at the signal terminal with key on
  • Open circuit may show floating or erratic voltage
  • Sensor ground continuity: near 0 ohms to vehicle chassis ground

Diagnostic algorithm

  1. Retrieve and note all codes, freeze frame, and live PID values. Verify P213D is current and if it repeats after a key cycle.
  2. Visually inspect throttle/EGR body connector and wiring for damage, overheating, corrosion, or pin push-out. Repair any obvious damage.
  3. With key ON (engine OFF) backprobe the sensor B signal pin. Confirm 5V reference and ground present at connector. Measure signal voltage; if near battery voltage or abnormally high, suspect short to VB or failed sensor.
  4. If signal reads high, disconnect the sensor connector and measure voltage at harness side. If high remains at harness, investigate upstream wiring (short to 12V) and repair wiring/connector.
  5. If harness signal is OK with connector disconnected, test the sensor itself: check internal resistance per manufacturer spec or substitute a known-good throttle/EGR unit if available.
  6. Perform wiggle and load tests while monitoring live PIDs to find intermittent opens/shorts. Repair damaged wires, secure connectors, and replace if necessary.
  7. After repairs or replacement of components, clear DTCs and perform functional tests/driving to confirm the code does not return.
  8. If wiring and sensor pass and code persists, consider PCM input scan or replacement as a last resort per manufacturer guidance.

Likely causes

  • Contaminated/corroded connector causing high resistance or short to 12V
  • Broken insulation or chafed wire contacting battery voltage
  • Failed throttle/EGR position sensor (internal short to Vb)
  • Loose or disconnected sensor ground or 5V reference feed

Fault status

⚠️ Status
EGR throttle control circuit B voltage high — inspect wiring, connector, and sensor.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
