Meaning of DF engine trouble code is a kind of and when your car's 'DF Check Engine' light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.

But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off.

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.

If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

Is the fuel pump sometimes not priming when you turn the key to ON II? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above. DF the main thing to check is to verify the operation of the VCT solenoid.

Autodijagnostika alati, ECU, senzori. Renault Megane 2, safe mode. Tema: Renault Megane 2, safe mode. Problem je taj da auto ulazi u rezervni rezim rada i to vrlo cesto pogotovo pri vecim obrtajima motora, tad slabo prima gas i slabo vuce. Na instrument tabli pali MIL, kljucic i na displeju ispisuje check injection. Zatim radjena dijagnostika orginalnom dijagnostikom, kaze dve greske vezane za EGR i treca koja prouzrokuje ulazak u safe mode a vezana je za Exhaust gas temperature sensor sonda.

Na autu vidim da postoji ta sonda na kucistu turbine i naravno dve sonde pre i posle DPF-a. Dali je u pitanju ta sonda instalacija provjerenanesto oko ispravnosti i zacepljenosti DPF-a? Ako neko moze da pomogne u ukaze na moguce probleme? Zacepljenost DPF se meri davacem diferencijalnog pritiska koji meri razliku pre i posle DPF i jedini je validan parametar za to.

Ima varijanta tog davaca sa samo jednim vodom dok je drugi otvoren ka atmo pritisku. Ako bude trebalo reci cu ti koje su granicne vrednosti. Kao sto znas EGT se koristi za merenje temp. Razliciti sistemi se ponasaju razlicito pri rezervnim LIMP rezimima.

Na tvom mestu ja bih merio voltazu EGT. Recimo sa iskljucenim davacem trebalo bi da imas odredjenu voltazu iz ECU-a i da li bi bilo i kakve promene kad ga ukopcas? Sem toga,to je lakse i brze nego meriti zice do ECU-a zar ne? Idem,cucemo se Odg: Renault Megane 2, safe mode po ovom sto je dijagnostikovano neispravan je egr i stalno zatvoren. Moze li EGR podici toliko temp. Postoji kod greske i za EGT. Pitanje je koji kod greske ogranicava snagu motoru?

The sensors receive a 5 volt reference signal from the PCM. As pressure readings change, the sensor varies the voltage and the computer reads that to determine input. In the case of a broken wire, the sensor never sees the voltage and the computer assumes a major fault.

So if you get this DF code, first check to make sure you're getting a good 5 volt reference signal at the sensor.

Remove the air filter box assembly so you can access the transmission range switch. Turn the key to the ON position, but do not start the vehicle. Move the shifter to the neutral position.

Align the alignment holes between the switch and the shift lever. Insert a 5mm drill bit into the adjustment hole to verify the proper alignment for the neutral position. Excessive air inflow can be caused by a vacuum leak, a dirty sensor or, an exhaust gas recirculation valve not closing properly. If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator.

I can help you but only if you want me to help you All the questions should start from what car, what year, what engine is what fuel.

What are the symptoms of the problem. Only then is what you know, what fault code, live data, what you have done. Thanks for the help guys. I haven't checked all the wiring to the EGR solenoid yet, initially I was focusing on why there's 3v on Pin 5 the solenoid earth.

I will check the others. Does anyone know why there would be 3v on that pin? It appears that it's coming from the ECU not bleeding across from loom damage.

I haven't made a note of the air flow meter reading but I can and will do. What bugs me is that the fault comes back without even starting the engine so I was thinking that it must be a wiring fault.

Thanks for the attachment, I'll look through it tonight. Originally Posted by steelcityuk. Below is summary of information from Clip.

Now the weird part: after the EGR valve replacement function is executed, the PR and PR values should read 0, at least in the way I understand it.

But despite the function being flawless executed, the values remain the same, e. And of course the error pops up again once the car is restarted. I can't figure out what is causing such behaviour. Wiring was damaged, but has been repaired and is now - as far as I can tell - intact. Any help is appreciated.You're looking for a sticking or stuck VCt solenoid valve caused by contamination.

The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool.
