Delphi Engine Management. 

Winning the Battle Against the Check Engine Light. 

Smart OE Engineering for Even Smarter Parts.

As a leading OE manufacturer of engine management systems, we build our OE expertise into every product, for smart parts that deliver improved emissions control, fuel economy, and driveability. Take our planar oxygen sensors – they deliver the industry’s fastest activation time. As quick as six seconds. But that’s just one example. We make many more equally smart parts. From MAF to MAP, crank to knock, cam to ABS sensors, to name but a few. And we supply these OE applications for the world’s leading vehicle manufacturers including Alfa Romeo, Fiat, Hyundai, Kia, Lancia, Opel/Vauxhall, PSA, Renault and Volvo.

A Rapidly Growing Aftermarket Opportunity.

The electronic content on new vehicles continues to rise at a rapid rate. In the 1980’s, 15% of a vehicle’s value was electronics. Today that number is 40% and growing. For any vehicle, this means that a significant sum is tied into the vehicle electronics alone. It also means a substantial repair opportunity for garages equipped with the right parts, tools and skills. Delphi is ready. Are you?

The Delphi Difference.

  • Full systems expertise: integrated systems and components.
  • Patented, innovative OE technology.
  • OE tested and calibrated to meet or exceed OE requirements.
  • Subjected to rigourous testing for durability, performance and environmental compliance.
  • Aftermarket portfolio of over 1,400 parts.
  • Maximum coverage and reduced inventory with consolidated SKUs.
  • OE-level training with courses such as essential electrics, engine management and multiplex.
  • Delphi DS tool offering advanced engine management diagnostics including reset adaption (post renewal of throttle body, MAP, MAF etc.), adjust/reset of the throttle actuator and EGR valve coding.

A Closer Look at Delphi Planar O2 Sensors. 


A- Dual-Layer Protection Shield  

Provides long-lasting, reliable operation during sensor life. 

B- Exclusive Poison-Protection Coating 

Protects elements from contaminants which can trigger ‘check engine lights’ and premature sensor failure.

C- Planar Sensing Element with Integrated Heater

Delivers the industry’s fastest light-off time to reduce cold-start emissions and improve fuel economy.

D- Stainless Steel Housing 

Tested for durability, performance and environmental compliance; up to 15 years/150,000 miles.

E- Breathable Membrane Filter 

Forces a better air supply to the centre portion of the sensor for optimal functionality.

D- High-Temperature Water Seal 

Resists high temperatures, vibration damage and wire corrosion to protect signal accuracy, and provide a longer sensor life. 

Tech Tips for Fewer O2 Comebacks.

> After determining a sensor needs replacement, be sure to correctly identify it before replacing it. The primary sensor is on the manifold or the exhaust pipe, newer vehicles have sensors downstream.

> When unplugging the wire connection, spray penetrating lubricant onto the threaded connection to facilitate removal.

> Always use an appropriate oxygen sensor tool to help remove the sensor.

> Use anti-seize on the threads of the new sensor. Most oxygen sensors come with a special electrically conductive anti-seize compound applied to the threads, so simply thread the new sensor into the void left by the old one. If not, apply the anti-seize included with the sensor.

> Tighten the sensor to the correct torque. When no torque value is given, treat it much like you would a spark plug. In other words, less is probably better.
