Measurement configuration

Wideband oxygen probe for a compatible air-fuel measurement controller.

A replacement oxygen-sensor listing for an AEM wideband system. A bare LSU sensor requires the correct heater and pump-cell controller. The Bosch LSU 4.9 datasheet is provided as a technology reference; it does not identify this item as LSU 4.9 or establish an AEM replacement part number.

PRODUCT-SPECIFIC CHECKS

Identify the probe part number and receiving controller.
Confirm connector, heater / control requirements and calibration.
Check thread, cable reach and exhaust installation requirements.

02 / JXPOWER

Specifications & configuration checks

Identify the actual unit and revision before relying on a technical value. The quote confirms the requested sales configuration.

Item scope: Sensor only unless the quote states a complete controller kit
Version identification: Bosch and AEM part numbers; LSU 4.2 / 4.9 identity to confirm
Electrical signal: Pump-cell sensor requiring a compatible wideband controller
Connector / termination: Connector key, pinout, calibration resistor and lead length must match
Mounting / routing: Confirm exhaust bung thread and controller installation instructions

Reference specifications describe the documented model, not an inspected supply unit. Match the hardware and package before ordering.

Details to confirm before ordering

Supply the label, hardware revision and connector photographs so the supplied unit can be matched to this reference.

03 / JXPOWER

Compatibility & requirements

Match the exact hardware, connection and application. A model name, vehicle name or connector shape alone does not establish compatibility.

Identify the probe part number and receiving controller.
Confirm connector, heater / control requirements and calibration.
Check thread, cable reach and exhaust installation requirements.

Bring your existing setup

Compatible receiving controller and calibration
Correct supply, signal wiring and connectors
Application-specific mounting / pressure or exhaust connections

What’s included — define the package

Included: confirm in the quote

Confirm probe and lead contents. Do not assume a controller, gauge or complete kit is supplied.

Required separately: check your installation

Compatible receiving controller and calibration
Correct supply, signal wiring and connectors
Application-specific mounting / pressure or exhaust connections

Optional: discuss your application

Pigtail, mounting pieces or additional monitoring if outside the quoted contents

These are package checks, rather than a guaranteed bill of materials. Your quote lists the actual supplied parts and quantities.

05 / JXPOWER

Installation & software

Match the controller model and specified sensor part number before connecting power. Keep the sensor connector and calibration element intact; route away from exhaust heat and water traps.

Questions about Wideband Oxygen Sensor

Can LSU 4.2 and 4.9 be interchanged?

Do not interchange them without explicit controller support and configuration. Their heater / pump-cell control and calibration requirements differ.

Can the sensor output go directly to an ECU 0–5 V input?

No. The compatible wideband controller operates the sensor and produces the analogue or CAN measurement used by the ECU.

Does a sensor include its controller and wiring?

A probe, signal controller, gauge and complete kit are distinct items. Ask for each included component and quantity; do not infer kit contents from a photo.
