P0216 is a semi-manufacturer-specific OBD-II Diagnostic Trouble Code (DTC) defined as Injector Timing Control Circuit/Open. For Land Rover diesel vehicles—specifically the Discovery 4 (L319) equipped with the 3.0 TDV6 (276DT/306DT) engine—this code triggers when the Engine Control Unit (ECU) detects an open circuit, short circuit, or intermittent electrical signal in the injector timing control circuit that regulates fuel injector firing timing.
In Land Rover’s 3.0 TDV6 twin-turbo diesel engine (standard in 2009–2016 Discovery 4), the injector timing control circuit syncs fuel injector activation with crankshaft/camshaft position to optimize combustion efficiency, reduce emissions, and maintain power delivery. An open/intermittent circuit disrupts this synchronization, leading to misfiring, reduced power, and increased diesel particulate matter (PM) emissions—violating EU6 emissions standards for Land Rover’s luxury SUV lineup.
Impact on Land Rover Discovery 4 Operation
For Land Rover Discovery 4 3.0 TDV6, P0216 forces the ECU into "limp home mode": it limits engine RPM to 3,000, disables turbo boost above 1,800 RPM, and shifts the engine to a "safe combustion map" to prevent damage. Extended driving with P0216 causes cylinder misfires (most common in cylinders 4–6), increased fuel consumption (15–20% drop in MPG), and eventual failure of the injector driver module (IDM)—a critical and costly component in Land Rover’s TDV6 engine (replacement cost: €1,200+ at Land Rover dealers).
2. Common Causes in Land Rover Discovery 4 3.0 TDV6
P0216 in Land Rover Discovery 4 is linked to electrical faults or mechanical wear unique to the 3.0 TDV6’s injector timing control system. Real-world diagnostic cases from ICARZONE’s Land Rover specialist technicians include:
- Open Injector Timing Control Wiring Harness (Discovery 4 2012) – UR1000 circuit testing revealed a broken wire in the injector timing control harness (near the engine firewall); repairing the 18-gauge wire with Land Rover-spec heat-shrink tubing restored signal continuity and cleared P0216.
- Faulty Injector Driver Module (IDM) (Discovery 4 2013) – UR1000 live data showed no voltage output from the IDM to injectors 4–6; replacing the OEM IDM (#LR012597) resolved P0216 (a top failure point in high-mileage 3.0 TDV6 engines).
- Corroded Injector Connector Pins (Discovery 4 2011) – Water intrusion in the engine bay (common in Discovery 4’s off-road use) corroded injector timing control pins; cleaning pins with electrical contact cleaner + dielectric grease eliminated intermittent signal loss and P0216.
- Failed Crankshaft Position Sensor (CKP) (Discovery 4 2014) – Inaccurate CKP sensor readings (#LR000699) caused the ECU to misinterpret injector timing, triggering P0216; replacing the CKP sensor restored precise timing synchronization.
- Damaged Injector Solenoid Windings (Discovery 4 2010) – Overheating (common in twin-turbo TDV6) damaged injector solenoid windings; replacing the affected injector (#LR032067) fixed P0216 and eliminated cylinder misfires.
- ECU Software Corruption (Discovery 4 2015) – UR1000’s "ECU Calibration Check" found outdated firmware (version L319_10.01.22); reflashing to the latest calibration (L319_10.03.45) resolved P0216 software-triggered errors.
3. Key Symptoms of P0216 in Land Rover Discovery 4
P0216 presents Land Rover/TDV6-specific symptoms that worsen under load (off-roading, towing, uphill driving) or cold starts (common in European climates):
- Check Engine Light illuminated (often paired with P0200 "Injector Circuit Malfunction" or P0335 "CKP Sensor Circuit" codes)
- Engine misfires (noticeable rough idle, especially at 1,000–1,500 RPM) – most prominent in cylinders 4–6 of the TDV6
- Loss of power (20–30% reduced torque) during acceleration – Discovery 4 owners report "sluggish" performance above 60 km/h
- Turbo lag (3–4 seconds) – twin turbos fail to spool due to incorrect injector timing
- Excessive black smoke from exhaust (unburned fuel) – a telltale sign of P0216 in TDV6 engines
- Limp mode activation (3,000 RPM limit, max speed 80 km/h) in severe cases
- UR1000 live data showing "Injector Timing: Out of Sync" or "Timing Control Voltage: 0V (Open Circuit)"

Use the ICARZONE UR1000 (with Land Rover/Jaguar diagnostic protocols) to accurately diagnose P0216 and avoid unnecessary injector replacement (the #1 mistake for Discovery 4 DIYers):
| Step | Action with UR1000 (Land Rover Mode) | Goal | Pass/Fail Criteria (Land Rover Spec) |
|---|---|---|---|
| 1 | Full System Scan > "Engine Control Unit (ECU)" > "Land Rover TDV6 Codes" | Verify P0216 and check for related TDV6 codes (P0200, P0335, 00883) | Pass: Isolated P0216 | Fail: Multiple injector/CKP codes (IDM failure) |
| 2 | Live Data > "Injector Timing Control Voltage/CKP Sync" | Monitor injector timing circuit voltage and CKP-injector sync | Pass: Voltage 9–14V, sync ±1° of target | Fail: Voltage 0V (open circuit), sync ±5°+ |
| 3 | Circuit Test > "Injector Timing Control Circuit Continuity" | Test for open/short circuits in the timing control harness (Land Rover spec) | Pass: Continuity (0–0.5Ω resistance) | Fail: Infinite resistance (open circuit) or <0Ω (short) |
| 4 | Active Test > "Injector Timing Control Solenoid Test" | Manually test injector timing solenoid operation (Land Rover exclusive function) | Pass: Solenoids activate (audible click) | Fail: No response (solenoid/wiring issue) |
| 5 | ECU Software Check > "Land Rover 3.0 TDV6 Calibration Version" | Verify ECU has latest P0216-related firmware (Land Rover TSBs) | Pass: Calibration ≥L319_10.03.45 | Fail: Outdated version (requires reflash) |
Case Example: 2013 Land Rover Discovery 4 3.0 TDV6 with P0216 – UR1000 live data showed injector timing control voltage at 0V (open circuit) and CKP-injector sync off by 7°. Circuit testing revealed a broken wire in the timing control harness (near the turbocharger heat shield) – repairing the wire with Land Rover-spec heat-resistant insulation restored voltage to 12.8V and sync to ±0.8°, clearing P0216 without IDM/injector replacement (saving €850 in OEM parts).
Diagnose P0216 (Land Rover) with UR10006. Fixes & Execution for P0216 (Land Rover Discovery 4 Specific)
Repair strategies for Land Rover must follow OEM specs—target the root cause (not just injectors) to avoid recurring P0216:
- Injector Timing Control Harness Repair (Land Rover OEM Only) – Replace damaged wires with Land Rover-spec 18-gauge heat-resistant wire (rated to 200°C, part #LR001245). Use OEM heat-shrink tubing (#LR000897) to protect against turbo heat.
- Injector Driver Module (IDM) Replacement – Install OEM IDM (#LR012597) and perform "IDM Adaptation" via UR1000’s Land Rover ECU menu (requires 15-minute idle + 20-mile test drive).
- Injector Connector Pin Repair – Clean corroded pins with Land Rover electrical contact cleaner (#LR002345) and apply dielectric grease (#LR001987) to prevent future corrosion.
- Crankshaft Position Sensor (CKP) Replacement – Install OEM CKP sensor (#LR000699) and perform "CKP-Injector Sync Calibration" via UR1000 (critical for TDV6 timing accuracy).
- ECU Reprogramming (Land Rover Flash) – Use UR1000 to install the latest Land Rover 3.0 TDV6 ECU calibration (critical for 2010–2014 Discovery 4 with P0216 software bugs).
- Fuel Injector Replacement – For damaged solenoid windings, install OEM injectors (#LR032067) and torque to 28 Nm (20.7 ft-lbs) per Land Rover specs.
Land Rover Discovery 4 Model-Specific Tips
- Discovery 4 3.0 TDV6: Access the injector timing control harness from the passenger side of the engine bay (remove air intake box) – avoid removing the turbocharger (saves 4+ hours of labor).
- 2010–2012 Discovery 4: After IDM replacement, run "Fuel System Adaptation" via UR1000 to reset injector timing maps (prevents rough idle post-repair).
- Off-road Discovery 4: Inspect injector wiring harness after off-roading – mud/water intrusion is the top cause of P0216 in off-road-focused vehicles.
7. Repair Costs & Safety Tips (Land Rover)
Critical Land Rover Safety Precautions
- Disconnect the negative battery terminal (Discovery 4: 12V in engine bay fuse box) before working on injector timing circuits to avoid ECU/IDM damage (Land Rover ECUs are highly sensitive to electrical shorts).
- Use a Land Rover-spec torque wrench when installing injectors/CKP sensors – over-tightening damages injector seats (common in TDV6 engines) or CKP sensor alignment.
- Allow the TDV6 engine to cool completely (5+ hours) before working on injector wiring – turbocharger temperatures exceed 550°C, causing severe burns.
- After repairs, use UR1000 to clear Land Rover-specific fault codes (not just generic OBD-II codes) to prevent P0216 recurrence.
- Avoid off-roading/towing until P0216 is fixed – limp mode reduces engine cooling, increasing risk of injector overheating (€500+ per injector repair).
8. Preventive Maintenance for Land Rover Discovery 4
Avoid recurring P0216 in Land Rover Discovery 4 3.0 TDV6 using these Land Rover-recommended maintenance steps (backed by ICARZONE’s Land Rover specialists):
- Inspect injector timing control wiring every 40,000 km (25,000 miles) – focus on corrosion/abrasion near the turbocharger heat shield (Discovery 4’s engine bay hot spot).
- Replace diesel fuel filters every 20,000 km (12,400 miles) – contaminated fuel damages injector solenoid windings (a top cause of P0216 in TDV6 engines).
- Use UR1000’s "Land Rover TDV6 Health Check" quarterly to monitor injector timing voltage and CKP sync – catch anomalies before P0216 triggers.
- Keep ECU software updated via UR1000’s free lifetime Land Rover firmware updates – Land Rover regularly releases fixes for P0216 logic errors in 3.0 TDV6 engines.
- Apply Land Rover OEM dielectric grease (#LR001987) to injector connectors during service – prevents water/mud intrusion (critical for off-road Discovery 4 owners).
