Engine Malfunction Light Came On And Flashing "trc Off" Ligh

Last week, these lights came on. Lights disappeared after a couple of days, however I still took the car to my local garage for diagnosis, result was a "P0505 Idle Control Malfunction". The mechanic said that the fault could be from one of the three parts (cannot remember exactly, it was on their reference book).

After driving the car fro about 100 miles in few days, same lights on the dashboard re-appeared today. There is no change on performance and fuel consumption and no misfire as well. Has this happened to anyone? I've searched the topics but people who experienced the same problem turned out to be their coil pack and others didn't bother replying once their problem got sorted. Could this fault code "P0505 Idle Control Malfunction" be the coilpack even the mechanic said that it's not. He suggested to use one of those fuel treatment that cleans the engine fuelling system. It's just annoying driving with those lights on the dashboard.

I would also like to purchase one of those OBDII reader from ebay, can anyone suggest a cheap one that will do the job. How good are those ones that doesn't need plugging into a laptop, reason being not having a laptop myself.

Your help will be appreciated. Thanks.

I have been a mechanic 20 years and even i use one of the cheap obdII readers. Just fr a quick plug in and get fault codes. The one i use comes from Argos although i have had it 2 years. It doesnt always give all the fault codes and sometimes i have to use on of my other diag kits as well. I also have an Autodata cd which i use to double check the fault code.

Most garages charge about 30 quid for a plug in so if you buy one and use it twice your quids in. I currently have alot of Vauxhalls with engine lights on, they show a Lambda sensor fault code. This is a sensor in the cars exhaust which detects a bad burn in the engine. Every single one i have found has a comman link they all use super market petrol from the same branch of Tesco. I use my little obdII reader to turn the light out and the fix is just not to use Tesco petrol. I dont charge for this fix and usually get repeat custom from it. so for me they worth the money. i think the one i bought was abotu 30 quid.

    • 10 years of Lexus design: from spindle grille to spindle body
      After 10 years as a defining style feature of every new Lexus model, the famous spindle grille is undergoing a transformation. In tune with a new era of electrified vehicles, the distinctive shape is evolving into a new “spindle body,” as seen on the upcoming new generation Lexus RX SUV and the all-electric RZ.

      The spindle grille has been an unmistakeable Lexus feature since it was first revealed on the LF-Gh concept model of 2011, the basis for the fourth generation GS executive saloon that was launched the following year. Since then, it has been constantly adapted to suit the character of each successive Lexus model, with different mesh patterns, dimensions and finishes.


      Speaking at the time of the grille’s debut, the then Head of Lexus Kiyotake Ise said: “You should be able to identify a car as a Lexus immediately… Instant visual recognition, for example, is the reason behind our spindle grille. It may look aggressive at first glance, that’s intentional, but it also conveys its boldness with sophistication and elegance.”


      It has progressed to become a hallmark expression of Lexus’s L-finesse design, adopted not only for road-going cars, but also incorporated in the futuristic Skyjet spacecraft created for the Lexus-supported movie Valerian and the City of a Thousand Planets and adopted as a design motif in the Loft, the award-winning Lexus and Brussels Airlines lounge at Brussels Airport.


      Today, the original grille concept is the starting point for a more radical application of the spindle shape in which it becomes an integral part of the vehicle’s overall design. This “spindle body” approach is part of the Lexus Next Chapter design for the all-new RX, where the grille is reinterpreted as a seamless unit that flows into the bodywork. The lower section retains a mesh pattern, while the upper section takes in the lower edge of the bonnet; the Lexus emblems sits at the centre of the spindle’s high pinch-point.


      The same concept has been applied to the RZ 450e. As a battery electric vehicle, this requires less cooling than a car with a conventional engine, so the grille has been dispensed with, giving the designers greater freedom. Nonetheless, the spindle shape remains prominent in a central front panel, finished in the car’s body colour. Its impact is heightened by the adjacent frontal areas being contrast-finished in black, the low bonnet line and more boldly shaped front wings.

      On both models, the spindle generates lines that flow back from the front of the car through the bonnet and headlamp units to create a strong and distinctive frontal appearance, reinforcing the brand-defining ambitions of the original concept.
