Suitable for Mazda MX-5 Mk3.5 / Mk3.75 (NC) 1.8 and 2.0 petrol models, with application data specifying vehicles from September 2008 production. This is the pre-catalyst / upstream regulating sensor.
DENSO DOX-0560 is a Direct Fit heated broadband oxygen / lambda sensor for later Mazda MX-5 NC applications. It is supplied with the correct vehicle-specific electrical connector and wiring arrangement, allowing direct replacement without adapting or soldering a universal sensor into the original wiring loom.
This sensor is positioned before the catalytic converter and operates as the regulating sensor within the engine-management system. It monitors the oxygen content of the exhaust gases so the ECU can accurately control the engine's air-fuel mixture.

Important Fitment Note
DOX-0560 is the later upstream / pre-catalyst sensor, with application data specifying vehicles from September 2008 production. Earlier MX-5 Mk3 / NC1 vehicles use a different upstream sensor specification, including DENSO DOX-0518 on the corresponding earlier applications.
DOX-0560 must also not be confused with the downstream / post-catalyst diagnostic sensor. The upstream and downstream sensors perform different functions and are not interchangeable.
Typical Reasons for Replacement
An oxygen / air-fuel ratio sensor may require replacement because of internal sensor deterioration, heater-circuit failure, contamination, damaged wiring or connector problems. A failed sensor can contribute to an engine-management warning light, incorrect mixture control, poor running or increased fuel consumption, although these symptoms can have other causes and should be correctly diagnosed before replacing components.
Fitment Advice
Confirm that the sensor being replaced is the upstream / pre-catalyst sensor before removal. Where necessary, compare the connector, cable arrangement and original Mazda part number with the existing component.
For imported, modified or previously repaired cars, matching the part number or component style on the part being replaced is recommended.
Other Items to Consider
- Downstream / post-catalyst oxygen sensor if separately required
- Exhaust manifold and exhaust gaskets
- Exhaust-system fasteners
- Ignition components where poor running is being investigated
- Routine engine service components where appropriate
Useful Tools / Consumables
- Suitable oxygen / lambda sensor socket
- Ratchet and extension as required
- Torque wrench
- Penetrating fluid where appropriate for seized exhaust threads
Difficulty Guide
DIY Difficulty: Moderate. The sensor is threaded into the exhaust system and may become difficult to remove after prolonged exposure to heat and corrosion. Correct identification of the sensor position and careful handling of the electrical connector are important.
Why DENSO?
DENSO is a long-established Japanese automotive component manufacturer with extensive experience in engine-management and emissions-control technology. Its Direct Fit oxygen and air-fuel ratio sensors are application-specific replacements supplied with the appropriate connector and wiring configuration, drawing on DENSO's extensive automotive engineering experience.
What's in the Box?
- 1 x DENSO DOX-0560 Direct Fit oxygen / lambda sensor
Installation Notes
Allow the exhaust system to cool before starting work. Disconnect the electrical connector before removing the existing sensor and avoid twisting or damaging the wiring during installation.
The replacement sensor is supplied with a pre-treated thread. Take care not to contaminate the sensing element and tighten the sensor using the appropriate installation procedure.
