In a few words: The EPC warning light comes on to indicate that there is a problem with the electronic system that controls the engine. You should take into account that the problem may go from a burnt out headlight bulb to throttle failure. For this reason, trying to find the problem any other way may be a troublesome task. In these cases, the throttle will have a TPS Throttle Position Sensor and an actuator electric engine , that is to say, there are no mechanical connections between the throttle and the engine of the car. As a consequence, the EPC is in charge of the regulation of the throttle body according, mainly, to a signal sent by the throttle sensor. This is how fuel consumption and emissions are decreased. This system is also powered by the signals of auxiliary sensors such as the crankshaft position sensor CKP , the manifold absolute pressure MAP sensor, the mass air flow MAF sensor and the knock sensor, among others. This warning light will turn on briefly when you turn the ignition key and then it will turn off, which indicates that the light works properly. If the warning light is still on even after the car has been started or if it comes on while you are driving, that means that there is a problem with the acceleration system. In addition, your car may jerk, have combustion issues or loss of power.

He said if I hadn't done what I had done we may have never have found it, or worse, it could have blown off whilst going down a motorway etc. Felt like I'd hit a wall. Post by monkeyhanger » Fri Apr 03, pm I just had an email from my supplying dealer Listers asking if I'm a key worker in need of essential maintenance, so it seems that some garages are keeping their service departments open on a reduced service. Turned the car off and back on but the lights are still there and the issue still remains. In addition, your car may jerk, have combustion issues or loss of power. Tried it back in Sport, but no real power and it revs really slowly. He was amazed I'd had no problems until now and I just said "I usually drive like miss daisy and no boost".

Happy days. Because of this, you will not be able to accelerate. Quick links. This is how fuel consumption and emissions are decreased. Log in Sign up. Post by monkeyhanger » Fri Apr 03, pm Sounds like the MAF sensor thinks the car is getting more or less air than it actually is and either getting an implausible value and reverting to limp mode if it does that immediately on the fly, that could be your "thump" - massive engine braking effect from a car that is suddenly starved of fuel at rpm in a low gear. If it's literally a tenner and can easily be removed and reinstalled, might be better than trying to put it in the garage at this time. A new car like that if it has a problem now may as well get it out of the way instead of it happening months or years down the line.
