EXHAUSTS & EMMISIONS ADVICE FROM ELTA


24 Jun 2019

Category: Articles, Press Releases

Sensors in general, but for the complex control of the engine’s performance characteristics in particular, are a growing feature of the modern vehicle. A myriad of these electronic devices are now called on to work together to ensure the engine is functioning to its optimum efficiency and nowhere is this more evident than in the area of its exhaust control and emission levels.

 

“In-depth analysis conducted by our TECHASSIST support service indicates that there are two common reasons for returns,” says ELTA Automotive’s Marketing Manager, Tim Brotherton. “The first is misdiagnosis. There are several causes of EGR-related fault codes and not all point directly to the valve itself. The second is technicians replacing EGR valves, but not addressing the underlying issues that caused the valve to fail. Our research shows that EGR valves that have failed prematurely are often heavily contaminated, indicating that they’ve been installed into a ‘dirty’ system.”

 

To tackle this, ELTA recommends a three-step process. First, clean the system using an EGR/turbo cleaning aerosol or a Terraclean (or similar) system, second, replace the EGR valve and third, reset the ECU so it recognises the new component.

 

“Other components to check include the air mass sensor – as a faulty sensor may not be measuring the correct air flow rate – the throttle body – because if this is malfunctioning it may result in an insufficient amount of air entering the engine – and the vacuum pump – because pneumatically controlled EGR valves can fail to actuate if it is not operating correctly,” Brotherton continued.

 

“Using our TECHASSIST technical expertise, we are able to demonstrate that drilling down to find the underlying fault is the key to the correct prognosis and as well as yielding better results, following a structured procedure will improved workshop efficiency by saving time and money.

 

“Naturally, all the necessary replacement valves and sensors are available within the extensive engine management programme that falls under our VXPRO brand. These products are tested to ensure they operate within the manufacturer’s original parameters, therefore guaranteeing that there will be no change to the vehicle’s original performance following the installation of the part.

 

“In addition, the range also features QR codes on the packaging, enabling installers to access a quick link to product specific fitting and technical advice, without having to open the box.”
