06 December 2017 | Article

The Christmas period isn’t always the season of good cheer for motorists, as extreme weather conditions take their toll on the most vulnerable car parts, not least on Lambda Sensors. Best practice advice from DENSO helps make sure the only surprise customers receive comes wrapped under a Christmas tree.

Lambda Sensors can be one of the most important parts of a car, helping to ensure optimal engine performance and clean emissions. However, they are also one of the most vulnerable components, particularly if exposed to extreme weather conditions.

This can prove especially challenging during the winter period when conditions are at their worst, and old or low-quality components may start failing. Workshops with the expertise can easily reap the rewards by seizing on these additional opportunities and bolstering their customer service.

Replacing Lambda Sensors is one thing, but the challenge for many is selecting the right product, and fitting it correctly to ensure a happy, returning customer.

Direct Fit fitting

Before fitting it is important to prepare the relevant area, so ensure you have:

  • Cleaned the contact surface for the gasket and the thread with a thread cleaning tool.
  • Checked the wiring loom for broken wires that have been melted or torn.
  • Checked the counter connector for signs such as housing damage, missing seals, dislocated pins, and the leakage of oil or water.

Once you have prepared the area, you can begin fitting the Lambda Sensor step-by-step:

  1. Screw the sensor in by hand, making sure not to cross the thread.
  2. Tighten to the torque specified. For DENS Direct fit, this is 35-45 Nm.
  3. Wire routing – if possible use the original fixation materials and positions. Sometimes DENSO provides alternatives in the box.
  4. If the wire is slightly too long, bind the cables as close to the connector as possible, and away from the exhaust and moving parts, without any folding.
  5. Finally, connect and lock the connector – you should hear an audible click.

By performing a thorough and comprehensive system check and service technicians can repair minor issues, and replace faulty sensors with OE quality to prevent more serious problems from occurring whilst providing an improved service to enhance customer satisfaction and in turn, retention.
