P0062 on 2013-2016 Land Rover Range Rover: HO2S Heater Circuit Fault Explained

What's Unique About the 2013-2016 Land Rover RANGE ROVER

For this generation of Land Rover Range Rover and its platform mates, the P0062 code is strongly linked to premature failure of the oxygen sensor itself. Multiple Technical Service Bulletins (TSBs) were issued by Land Rover, indicating a 'MANUFACTURING FAULT AT THE SUPPLIER' which led to 'misalignment within the sensor leading to side load on the ceramic internal to the sensor'. This internal pre-stress, combined with normal use, leads to premature failure, making it much more likely that the sensor is the root cause, rather than wiring or other issues. Another TSB also suggests the sensors are susceptible to failure from 'thermal shock when water contacts the heated sensing element'.

Symptoms You May Notice

• Check Engine Light is illuminated
• Vehicle will fail an emissions test
• Decreased fuel economy
• Rough idle or engine hesitation in some cases

Most Likely Causes

1. Faulty Heated Oxygen Sensor (Bank 2, Sensor 3) 🔴 High Probability Multiple manufacturer TSBs (SSM63157, SSM72448) point directly to a supplier manufacturing defect causing premature sensor failure. The defect caused a 'side load on the ceramic' element, and sensors manufactured before June 2013 are particularly suspect. Additionally, TSB LTB00671NAS3 notes failures can be caused by thermal shock from water contact.
   How to confirm: Using a multimeter, test the resistance of the heater circuit within the sensor (typically across the two same-colored wires). An open circuit (infinite resistance) or a reading far outside the manufacturer's specification (often 5-20 ohms) confirms the internal heater has failed.
   Typical fix: Replace the Bank 2, Sensor 3 oxygen sensor. 🎬 See this walkthrough for locating and fixing the P0062 code. This sensor is located on the driver's side, downstream of the catalytic converter, roughly under the driver's seat area.
   Est. part cost: $45-$150
2. Wiring or Connector Issue ⚪ Low Probability While less common due to the known sensor issue, the wiring harness is located under the vehicle and is exposed to heat, moisture, and road debris, which can cause corrosion or damage over time. TSB SSM72448 specifically notes that upon diagnosis, often 'NO FAULT IS FOUND WITH THE WIRING HARNESS OR CONNECTOR', pointing back to the sensor.
   How to confirm: Visually inspect the wiring and connector for the Bank 2, Sensor 3 O2 sensor for any signs of damage, melting, or corrosion. Check for 12V power and a good ground at the connector with the ignition on.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the corroded connector.
   Est. part cost: $10-$50
3. Blown Fuse or Faulty Relay ⚪ Low Probability A short in the sensor or its wiring can cause the associated fuse to blow, cutting power to the heater circuit.
   How to confirm: Consult the vehicle's owner's manual or fuse box diagram to locate the fuse for the O2 sensor heater circuits. Visually inspect the fuse and test for continuity with a multimeter.
   Typical fix: Replace the blown fuse. If the fuse blows again, it indicates a persistent short circuit in the wiring or the sensor itself that must be found and fixed.
   Est. part cost: $1-$10

Rare But Worth Checking

• Powertrain Control Module (PCM) Fault: This is extremely rare. The PCM should only be considered after the sensor and its entire circuit (wiring, connectors, fuse) have been thoroughly tested and confirmed to be in good working order.

Diagnosis Steps

1. Confirm the presence of code P0062 (and any others) with an OBD-II scanner.
2. If the vehicle has air suspension, raise it to 'Off-Road Height' for better access. Otherwise, safely raise and support the vehicle.
3. Locate the sensor under the car, on the driver's side exhaust pipe, rear of the catalytic converter, approximately below the driver's seat area.
4. Visually inspect the sensor's wiring harness and connector for any obvious signs of damage, melting, or corrosion.
5. Disconnect the sensor. With the ignition on (engine off), use a multimeter to verify that the harness-side connector is receiving approximately 12 volts for the heater circuit.
6. Test the ground connection on the harness-side connector.
7. If power and ground are present, test the resistance of the heater circuit on the sensor itself. A typical resistance is between 5-20 ohms, but an open circuit (infinite resistance) is a definitive sign of failure.
8. If the sensor's heater circuit tests bad, replace the oxygen sensor. A 22mm oxygen sensor socket is required for removal.
🎬 Watch this DIY replacement for L405 and Sport models.
9. If the wiring tests bad (no power or ground), trace the circuit back, checking the relevant fuse first, then looking for a break or short in the wiring.
10. After repairs, clear the code with the scanner and perform a drive cycle to ensure the fix was successful.

Related Codes That Often Appear With This One

• P0042 — Relates to the heater circuit for Bank 1, Sensor 3. It's common for these sensors to fail around the same time due to the shared manufacturing defect mentioned in TSBs.
• P0162 — This is a general malfunction code for the O2 sensor circuit at Bank 2, Sensor 3, and can appear alongside the more specific P0062 heater circuit code.
• P0061 — This is the equivalent heater circuit code for Bank 2, Sensor 2 (the mid-stream sensor). It's possible for multiple sensors on the same bank to have issues simultaneously.

Technical Service Bulletins (TSBs) & Recalls

• SSM72556: Confirms code definition as HO2S HEATER CONTROL CIRCUIT (BANK 2 SENSOR 3).
• LTB00671NAS3: Associates P0062 with post-catalyst heated oxygen sensors and suggests thermal shock as a cause.
• SSM72448: Suggests the fault is typically the sensor, not the wiring.
• SSM63157: Identifies a supplier manufacturing fault ('side load on the ceramic') as a root cause for sensor failure and provides affected part numbers and date codes.

Platform-Specific Known Issues

• TSB SSM63157 explicitly states the cause for this and related codes can be a 'MANUFACTURING FAULT AT THE SUPPLIER – MISALIGNMENT WITHIN THE SENSOR LEADING TO SIDE LOAD ON THE CERAMIC'. It advises checking the date code on the sensor and ensuring it is from June 1, 2013 or later.
• TSB LTB00671NAS3 groups P0062 with a long list of other codes related to 'POST-CATALYST HEATED OXYGEN SENSORS', confirming the location and widespread nature of the issue across multiple JLR models.
• TSB SSM72448 notes that when diagnosing these codes, often 'NO FAULT IS FOUND WITH THE WIRING HARNESS OR CONNECTOR', further pointing to the sensor itself as the problem.

Mechanic-Grade Diagnostic Values

• Heated Oxygen Sensor Heater Circuit Resistance — expected: Approximately 8-10 ohms when cold. A Bosch datasheet for a similar sensor specifies 9 ohms for a new part.. Failure: An open circuit (infinite resistance) or a reading significantly outside the 8-10 ohm range indicates a failed heater element.
• Heater Circuit Voltage Supply — expected: Approximately 12V with ignition on, engine off.. Failure: Voltage below 9V or no voltage indicates a problem with the fuse, relay, or wiring, not necessarily the sensor itself.

Scan Tool Commands That Help

• JLR SDD (Symptom Driven Diagnostics): Read Diagnostic Trouble Codes (DTC) — To confirm P0062 and identify any other related codes stored in the Engine Control Module (ECM).
• JLR SDD (Symptom Driven Diagnostics): Data Logger / Live Data — To monitor the voltage and operational status of the O2 sensors in real-time to confirm a lack of activity from the Bank 2 Sensor 3 heater circuit.
• JLR SDD (Symptom Driven Diagnostics): Clear All Stored Diagnostic Trouble Codes — After the repair is complete, this function is used to erase the fault code from the ECM memory. A drive cycle is then needed to confirm the fix.

Wiring & Ground Locations

• Engine Compartment Fuse Box — Located under the hood, on the passenger side of the vehicle. The cover must be removed to access fuses.. This fuse box contains the fuses for the oxygen sensor heaters. A label on the inside of the cover identifies fuse locations. Fuse F14 (20A) is listed for front oxygen sensors, and F11 (15A) is listed for rear oxygen sensors in some diagrams. Always verify with the vehicle's specific diagram.
• Main Body Ground Points — Key ground points are located on the inner fenders behind the battery and airbox on both the driver and passenger sides.. Poor ground connections are a common source of electrical faults on Land Rovers. Corrosion on these main grounds can cause intermittent or persistent circuit faults, including for sensor heaters. Cleaning these points is a critical diagnostic step for any electrical issue.

Real Owner Repair Stories

• landroverforums.com user (Range Rover L405 (year not specified, but within generation)) — Check Engine Light with code P0062.
  ❌ Tried (didn't work) Initial diagnosis pointed to the sensor.
  ✅ What actually fixed it The user replaced the Bank 2, Sensor 3 (driver's side, rear) oxygen sensor. They noted the original sensor was seized and required heat from a torch to remove. After installing the new sensor (Bosch LR098290) and clearing the codes, the issue was resolved.

OEM Part Supersession History

• LR035748 → LR098290, which was then superseded by LR136928 — Standard part evolution and updates by the manufacturer. The manufacturing flaw noted in TSB SSM63157 likely prompted the initial supersession.
  Heads up: The newer part numbers (LR098290, LR136928) are direct replacements for the original LR035748 and are fully compatible.
