Extended Product Information

FAQs

What is the primary function of a Lambda Oxygen Sensor?

A Lambda Oxygen Sensor measures the oxygen content in the exhaust gases. This information is used by the vehicle's computer to optimize the fuel-air mixture for efficient combustion, reduced emissions, and optimal engine performance.

How do I know if my oxygen sensor needs replacement?

Common signs include a check engine light, decreased fuel economy, rough idling, poor acceleration, and failed emissions tests. A diagnostic scan tool can often pinpoint an oxygen sensor fault.

Is this sensor a direct fit for all Ford or Jaguar models?

This sensor (DOX-1726) is designed as an OE-equivalent replacement and is compatible with specific Ford and Jaguar part numbers. Always verify compatibility with your vehicle's exact make, model, and year before purchasing.

What does 'heated' mean for an oxygen sensor?

A heated oxygen sensor has an internal heating element that brings it to its optimal operating temperature faster after the engine starts. This allows for more accurate readings sooner, improving emissions control, especially during cold starts.

Can I install this sensor myself?

Installation is possible for individuals with mechanical experience and the correct tools. However, if you are unsure, it is recommended to have it installed by a qualified automotive technician to ensure proper fitment and function.

What is the thread size of this sensor?

The thread size of the Denso DOX-1726 is M18x1.5, which is a standard size for many oxygen sensors.

Does this sensor come with an anti-seize compound?

The product information does not specify if anti-seize compound is included. It is generally recommended to use a small amount of appropriate anti-seize on the threads during installation, ensuring it is compatible with sensor coatings.

Troubleshooting

Check Engine Light remains on after installation

Ensure the sensor is correctly installed and the electrical connector is securely fastened. Clear the DTCs using a diagnostic scan tool. The issue might be related to another component or a persistent system fault.

Rough engine idle or poor performance persists

Verify the sensor is the correct part for your vehicle. Check for exhaust leaks before the sensor, as these can affect readings. Ensure all other engine components are functioning correctly, as the issue may not be sensor-related.

Difficulty in removing the old sensor

Apply a penetrating lubricant to the threads and allow it to soak. Use a dedicated oxygen sensor socket wrench for better grip. If seized, professional removal might be necessary to avoid damaging the exhaust pipe.

Setup, Compatibility & Care

Compatibility:

Before purchasing, it is essential to verify that the Denso Lambda Oxygen Sensor DOX-1726 is compatible with your specific vehicle's make, model, and year. Cross-reference the MPN (DOX-1726) and the provided OEM numbers (e.g., 1123897--FORD, 1639714--FORD, 1682753--FORD, 1743702--FORD, 1S7F-9F472-AB--FORD, 3010660--FORD, AE81-9F444-AB--FORD, AE81-9F444-AC--FORD, AE81-9F444-BA--FORD, AE81-9F444-BB--FORD, AE81-9F444-BC--FORD, XC2F-9F472-A1A--FORD, XC2F-9F472-AA--FORD, XR86938--JAGUAR) with your vehicle's specifications.

Setup:

  1. Safely lift and support the vehicle to access the exhaust system.
  2. Locate the old oxygen sensor, typically found in the exhaust manifold or pipe.
  3. Disconnect the electrical connector of the old sensor.
  4. Use an appropriate oxygen sensor socket wrench to carefully unscrew and remove the old sensor.
  5. Apply a small amount of anti-seize compound (if recommended and compatible with sensor coatings) to the threads of the new DOX-1726 sensor.
  6. Screw the new sensor into the exhaust port by hand to avoid cross-threading.
  7. Tighten the sensor using the wrench to the manufacturer's specified torque.
  8. Connect the electrical connector securely.
  9. Lower the vehicle and clear any diagnostic trouble codes (DTCs) with a scan tool.

Care:

Oxygen sensors are delicate components. Avoid dropping them or exposing the sensor tip to contaminants like oil, grease, or dirt. Ensure hands are clean before handling. Regular vehicle maintenance, including checking for exhaust leaks, will help prolong the sensor's life. It is recommended to have the sensor installed by a qualified mechanic if you are not comfortable performing the task yourself.
