Causes

Stuck or seized EGR valve or actuator (carbon build-up)
Faulty EGR position sensor or actuator (electrical failure)
Wiring faults: open, short to power/ground, or poor connector connections in EGR B circuit
Vacuum supply failure or pressure supply issue (if vacuum/pneumatic actuator used)
Restricted or leaking EGR plumbing/intake or exhaust passages
PCM software or calibration error

Symptoms

Malfunction Indicator Lamp (MIL) illuminated
Reduced engine performance, hesitation, or rough idle
Increased NOx/HC emissions and possible failed emissions test
Possible limp mode or derated performance on some vehicles
EGR-related diagnostic readiness monitor may be incomplete

What to check

Read stored and pending DTCs and freeze frame data with a capable scan tool; note occurrence and conditions
Check live data: commanded EGR position vs actual (EGR position feedback) while performing commanded actuations
Verify PCM detects and attempts EGR learn/adaptation; note learning count/limits if available
Visually inspect wiring harnesses and connectors for corrosion, damage, or water ingress at EGR B components
Inspect EGR valve/plumbing for carbon deposits, blockage, or mechanical sticking
Confirm vacuum/pressure supply and control solenoids (if applicable) are present and operating

Signal parameters

Commanded EGR position (%) or degrees
Actual EGR position feedback (%) or sensor voltage (V)
EGR actuator duty cycle or control voltage (V)
Position sensor resistance or voltage range (manufacturer spec)
Supply voltage to actuator/position sensor (approx. battery voltage)
Ground continuity and resistance to chassis ground

Diagnostic algorithm

Verify code: Connect OEM-capable scan tool, record DTC P049E and any related codes, capture freeze frame data.
Reproduce and observe: With a live-data tool, command EGR B to several positions and compare commanded vs actual position feedback. Note if actual follows command or is out of range.
Inspect wiring/connectors: With ignition off, visually inspect and perform wiggle test on connectors and harness to EGR B actuator/sensor. Repair any damage.
Power/ground and sensor checks: Measure supply voltage and ground at connector with key on; verify position sensor output is within expected range at rest and while commanding actuator.
Actuator function: Command the actuator from the scan tool and observe mechanical movement. If no movement, verify actuator receives command and power. If actuator moves but feedback is wrong, suspect sensor.
Mechanical inspection: Remove/inspect EGR valve and passages for carbon build-up or seizure. Clean if light to moderate carbon; replace valve if seized or excessively worn.
Bench test or swap: If suspecting actuator or sensor failure, bench-test or temporarily swap with a known-good unit if available.
Clear codes and perform adaptation: After repairs, clear DTCs and run the prescribed EGR relearn/adaptation procedure per Land Rover service information. Re-check for return of code.
Software and TSBs: If fault persists with good hardware, check for PCM software updates or known calibration fixes and apply as required.
Replace components: If diagnostics indicate component failure (actuator or EGR valve or harness), replace and verify proper operation and successful learning.

Likely causes

Carbon deposits causing EGR valve not to reach commanded position
Failed EGR position sensor reporting out-of-range values
Damaged wiring or connector to EGR actuator/position sensor
Actuator internal failure (electrical or mechanical)
Missing or incorrect adaptation values due to PCM needing an update or re-learn

Fault status

⚠️ Status

EGR B control position exceeded allowed learning/adaptation limits — EGR position feedback out of expected range. MIL set.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
