Hero Genuine Oxygen / O2 Sensor for HF 100, HF Deluxe, Passion Plus & Xtreme 125R | Lambda Sensor | 36532ACK001S

Hero Genuine Oxygen / O2 Sensor – 36532ACK001S

Restore accurate exhaust-gas feedback and closed-loop fuel control with the Hero Genuine Oxygen Sensor, part number 36532ACK001S. This model-specific exhaust sensor is used in compatible Hero HF 100, HF Deluxe, Passion Plus and Xtreme 125R fuel-injected applications.

The oxygen sensor is installed in the exhaust path and measures the oxygen content remaining in the exhaust gases. It sends an electrical signal to the engine control unit so the ECU can make fuel-delivery corrections and maintain the required air-fuel ratio during applicable operating conditions.

A slow, contaminated, open-circuit, short-circuit, physically damaged or incorrectly matched oxygen sensor can contribute to an engine warning lamp, unstable idle, hesitation, poor fuel economy, increased emissions, rich or lean running, difficult starting or an oxygen-sensor diagnostic fault. Similar symptoms can also be caused by wiring, exhaust leakage, injector, fuel pressure, ignition, intake leakage, engine compression or another sensor fault, so diagnosis is required before replacement.

This listing is for one oxygen/O2 sensor only. It is not the ECU, fuel injector, throttle body, exhaust pipe, catalytic converter, wiring harness or sensor mounting boss. The official retail record does not specify whether this SKU is heated or non-heated, so that construction must not be assumed from another Hero oxygen-sensor part number.

Compatibility Boundary

Hero uses several different oxygen-sensor part numbers across emission stages, engines, exhaust systems and ECU calibrations. A shared model name or visually similar connector does not guarantee compatibility.

No automatic compatibility is claimed for:

• Every HF 100 or HF Deluxe generation
• Early HF Deluxe i3S BSVI January 2020 applications using another oxygen-sensor number
• Every Passion, Passion Pro, Passion Plus or Passion XTEC generation
• Every Xtreme 125R generation without a chassis/VIN catalogue match
• Hero Splendor Plus applications using another oxygen-sensor SKU
• Hero Pleasure, Destini, Maestro Edge or Xoom scooter sensors
• Any engine whose catalogue specifies a different 36532-series part number

Fitment Note / Return Prevention Note

Before ordering, match the complete Hero part number 36532ACK001S or catalogue number 36532-ACK-001 with the motorcycle’s chassis/VIN-based exhaust, electrical and fuel-injection catalogue.

Confirm all of the following:

• Exact motorcycle model, variant and production generation
• BS6 / OBD emission-generation requirement
• Existing oxygen-sensor part number
• Sensor thread diameter and pitch
• Sensor body and probe profile
• Cable length and protective sleeving
• Electrical connector casing and locking tab
• Connector terminal count and pin arrangement
• Exhaust mounting location
• ECU and wiring-harness application
• Part number printed on the old sensor, package, invoice or service record

Heated Versus Non-Heated Warning

Hero catalogues both oxygen sensors specifically described as non-heated and other sensors listed simply as oxygen sensors. The official retail data for 36532ACK001S does not state heated or non-heated construction.

Do not identify this sensor by heated/non-heated terminology unless the exact vehicle catalogue, connector, wire count and original part confirm it. The complete SKU must remain the primary fitment reference.

Do Not Confuse It With Other Hero Oxygen Sensors

• 36532ACK001S / 36532-ACK-001 — oxygen sensor covered by this listing
• 36532-AAF-401 — separately catalogued non-heated oxygen sensor in selected earlier HF Deluxe and other applications
• 36532-AAE-311 — separately catalogued non-heated oxygen sensor for selected Splendor Plus applications
• 36532-ABS-201 — separately catalogued non-heated oxygen sensor for selected Pleasure Plus, Destini and Maestro Edge 125 applications
• 36532-AAW-B01 — separately catalogued non-heated oxygen sensor for selected Maestro Edge and Xoom applications

These oxygen-sensor numbers are not automatically interchangeable. Thread, probe, cable, connector, wire count, internal construction, response characteristics and ECU calibration can differ.

Diagnosis Before Replacement

An oxygen-sensor fault code or poor running condition can also be caused by:

• Loose, corroded or water-damaged sensor connector
• Broken, pinched, rubbed or heat-damaged wiring
• Exhaust leakage before or near the sensor
• Intake-manifold or vacuum leakage
• Weak fuel pump or incorrect fuel pressure
• Clogged or leaking fuel injector
• Dirty air filter or restricted intake
• Faulty spark plug, ignition coil or suppressor cap
• Low battery or charging-system voltage
• Incorrect valve clearance or low engine compression
• Contaminated fuel or excessive engine-oil consumption
• ECU, temperature-sensor or pressure-sensor fault
• Catalytic-converter or exhaust-system problem

Replacing the oxygen sensor alone will not repair an exhaust leak, wiring fault, fuel-pressure issue, ignition problem, worn engine or unrelated ECU/sensor fault.

Sensor Contamination Warning

Oxygen sensors can be damaged or contaminated by:

• Silicone-based sealants not approved for oxygen-sensor use
• Coolant or engine-oil entering the combustion chamber
• Lead, unsuitable fuel additives or contaminated petrol
• Excessive carbon caused by prolonged rich running
• Physical impact to the sensing tip
• Water entering an unsealed connector
• Incorrect cleaning chemicals

Do not clean the sensing tip with petrol, solvent, wire brushes, abrasives or compressed-air blasting.

Electrical and emission-component return protection: Confirm the exact part number before connecting or installing. Connected, energised, exhaust-fitted, heat-cycled, chemically cleaned, contaminated, scratched, modified or used sensors cannot be treated as unused returns.

Technical Details

Installation Note

Oxygen-sensor diagnosis and installation should be performed by a trained fuel-injection technician. The exhaust system becomes extremely hot and can cause severe burns. Allow the engine and exhaust to cool completely before removal.

Before Installation

• Read the diagnostic trouble code and freeze-frame data where supported
• Inspect live oxygen-sensor data according to the service procedure
• Check battery and charging-system voltage
• Inspect the sensor connector and wiring
• Check for exhaust leakage near the sensor
• Compare the old and new part numbers
• Compare the connector, wire count, cable length and probe profile
• Inspect the threaded mounting boss for damage
• Identify the root cause of contamination before fitting the new sensor

During Installation

• Disconnect the battery according to the vehicle service procedure
• Do not pull or twist the sensor by its cable
• Use the correct oxygen-sensor socket or tool
• Do not strike or touch the sensing tip
• Keep grease, oil and cleaning chemicals away from the probe
• Apply anti-seize only if specified and only to the threads
• Do not contaminate the sensing slots or sensor tip
• Start the sensor thread by hand to prevent cross-threading
• Tighten the sensor to the exact service torque
• Route the cable through the original heat-protected path
• Keep the cable away from the exhaust, sharp edges and moving parts
• Lock the electrical connector fully

After Installation

• Reconnect the battery and electrical system
• Clear related fault codes where required
• Start the engine and check for exhaust leakage
• Inspect live sensor operation after the engine reaches the required temperature
• Confirm stable idle and throttle response
• Verify that the engine warning lamp remains off
• Reinspect the wiring route and connector security

Do not operate the motorcycle if the sensor cable contacts the exhaust, the connector is loose, an exhaust leak remains or the original diagnostic fault returns without further investigation.
