Latest OE technology
Our ever-expanding range of ABS sensors features the latest digital signal technology. By creating a digital, square wave, Delphi magneto resistive and hall effect sensors only change frequency, not amplitude, improving accuracy, especially at lower speeds. They can also detect the direction of the wheels; forward, reverse and even stop. This is vital for hill hold control, autohold and automatic parking assistance technologies.
Protection from the elements
Given its position, the ABS sensor is particularly vulnerable to contamination from dirt and moisture. That’s why Delphi ABS sensors feature weather-pack connectors that lock out dirt, moisture, chemicals and other contaminants, coupled with plated pins for even great corrosion protection and improved conductivity.
Extreme testing
Water, heat and vibration can all affect a sensors characteristic. So we subject all our sensors to extensive thermal, shock and vibration testing just to be sure. With test temperatures ranging from -40 o C to 140 o C, we know they’ll perform even in the most challenging conditions. Delivering optimum stability and reliability at all times.
Easy installation
For right-fist-time fitment, Delphi ABS sensors are designed to match the OE. With like-for-like mounting and connector designs and wire lengths, technicians can fit quickly and easily, straight from the box.
The complete solution
As well as a growing range of ABS sensors, we also offer advanced diagnostic capability including the ability to read live fault codes and individual wheel speed data, essential repair data through our vehicle technical information package, and expert training and technical support.

Resource Highlights
NOx Sensors: An introduction
The Oxides of Nitrogen sensor is also known as a NOx sensor. It’s installed within a vehicle’s engine to test for the amount of oxides of nitrogen being emitted. The sensor then sends this information into the SCR system, which reduces the amount of NOx emissions.
A NOx sensor that isn’t working properly can be the cause of many problems within a vehicle’s performance such as rough idling or jerky acceleration.
What causes a NOx sensor to fail?
There are a few common causes of NOx sensor failure, which occurs when the sensor is no longer performing its role accurately – or at all. The most common NOx sensor failure reasons are soot build-up and heat damage.
It helps to determine which component has failed; the probe which detects the chemical makeup of the exhaust, or the sensor module which relays that information to the SCR system.
How to test a NOx sensor
Testing the NOx sensor will allow you to identify the reason it has stopped functioning properly. You’ll also get a good idea through a NOx sensor test what the best course of action would be.
Use a scanning tool to diagnose faults
A diagnostic tool like Delphi's BlueTech VCI can help you find out what faults have been reported by the onboard computer, if any. Plug in the tool and select the relevant ECU to pull up a list of reported NOx sensor fault codes.
Examples of common NOx sensor fault codes
OBD error codes ranging from P2200 to P2225 are the codes commonly associated with a NOx sensor fault. A NOx sensor error in Bank 1 is usually P2202. In Bank 2, it might be a P2213.
How to test a NOx sensor with a multimeter
Check the wiring diagram for the sensor to see which wires connect to the CAN, and which are for the power supply. Once you know which wires perform which task, use the multimeter to ensure there are no issues with the power supply.
In addition, test whether the CAN wires are in good enough shape to send data by testing them with an oscilloscope.
If the NOx sensor module passes these tests, it’s likely the issue lies with the sensor itself.
The NOx sensor is faulty – what should I do?
If testing the NOx sensor reveals a fault, you may need to replace the sensor and module. See our guide to replacing a NOx sensor to find out more about the process.
The NOx sensor isn’t faulty – what should I do?
If testing the NOx sensor concludes that there are no issues with the sensor itself, or the NOx sensor module, but the vehicle is still exhibiting problems or returning error codes, the problem is likely to lie elsewhere within the vehicle.
Another of the vehicle’s onboard sensors could be causing issues, such as the oxygen sensor or the air flow sensor . Faulty sensors relaying false information to the ECU – or no information at all – can cause erratic performance and damage the engine. Test the other sensors to check for issues.
