The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. When you fill your car with gas, the vapors in the tank get forced into a canister filled with activated charcoal. Also, on a hot day as the gas heats up and vaporizes, those same vapors push into the canister where they're stored. But the charcoal can only hold so much vapor.

At some point it has to be emptied. The emptying process is called canister purge. Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft.

If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.

The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter.

What you want to look any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature. All auto trouble codes with car brands.

It turns over but wont fire. Diagnostic also said left front wheel speed sensor but that shouldn't stop it firing up should it?

I took the back of the pump off and the shaft is still intact and pumping. If i fire easy start in the intake it tries to start but thats as far as it gets.

Ok,so you changed all the bits with dirty labels. What fuel pressure do you have at the injector rail? Also is the camshaft timing correct? It is not uncommon on these for the keyway in the camshaft sprocket to break and upset the valve timing.

When changing the MAF did the error code go away? Further try not connecting the MAF and see what happens. On live data it has good fuel rail pressure. Activated fuel sensors on diagnostics and they were ok. Check there are no stray earths or voltages appearing. Check the engine bay wiring loom for any chafing or tight bends.

Thanks in advanced and regards pinheiro. Reputation: Thanks in advanced and regards pinheiro Sure I've seen similar. The easiest way to check MAF is, to find someone who have same car and just swap sensors in moment of problem, but first check air filter and throttle valve. If I help you, please put reputation. The easiest way to check MAF is, to find someone who have same car and just swap sensors in moment of problem, but first check air filter and throttle valve Wrong my friend no MAF on lots of cars including this van I'm remember the boost sensor is part of the body or something.

Easiest way to check MAF? Sounds like one of the hardest ways bud No offence Scott. Hi This van hasn't got MAF! Reputation: 1. But it has a boost pressure sensor, located on the plastic inlet pipe, in a very low position, so the connector is very often full of water and wires become "green" oxidized.

So first, check this sensor and its wiring. Second thing, EGR valve, be sure that it is not blocked or clogged Third thing, connect the diag tool, drive the van and compare requested vs.

Coronavirus: Fuel stations at risk as demand for fuel collapses Petrol consumption is down by 75 per cent, with diesel dropping by 71 per cent, due to coronavirus. Latest Reviews 4.Your Renault Grandscenic engine control system detects a problem, the computer stores the diagnostic trouble code DF in its memory.

Another consequence of DF Renault Grandscenic engine overheating may be a blown head gasket. Heat makes aluminum swell almost three times faster than cast iron.

Thermal stress can distort the head and make it swell in areas that are hottest like those between exhaust valves in adjoining cylinders, and areas that have restricted coolant flow like the narrow area that separates the cylinders.

The typical aluminum head swells most in the middle, which can crush the head gasket if the head gets too hot. This will usually cause the head gasket to leak compression between adjacent cylinders, or leak coolant into the cylinders. While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the DF Renault Grandscenic code system was in four-cylinder mode.

In addition to these issues, while the company proposed a hydraulically controlled system that could be switched from within the car, the version they implemented had to be manually changed in the engine compartment using hand tools.Meaning of DF engine trouble code is a kind of and when the check engine light comes DF code on the first you should check is the gas cap.

Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off.

All you need to do is take the old one off and screw on the new one. If you've already made it to the store, you might as well just replace it. While not car-threatening, it's good to take care of this right away to improve gas mileage. Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Spark plugs typically need to be replaced every season or 25 hours of use.

You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. The oxygen 02 sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders.

Renault Espace 2. Flat Ascending Flat Descending Threaded. Forum Technician. Hi, got called out to an Espace 2. The owner said that it periodically loses power, the mil light comes on and the car will not respond for a while and then it comes back to life and is fine, I was unable to drive the car as it was blocked in but it is coming to my workshop for some diagnostics on thursday, I did scan the ecu and came up with: DF - air flow sensor, incoherence of data.

DF - EGR valve, positive loop difference. I have read that the EGR valve on these engines tends to coke up and stick but not had any experience of it myself, any suggestions on how to proceed with this fault?

Autodata don't give much info on this model! The dash also fails occasionally but I am sure that is a cluster fault, it may be off to BBA for some repairs in the near future. Any info appreciated. Posted Wednesday, July 08, PM. Start of by pulling the EGR off and de gungeing it Posted Thursday, July 09, AM. Will do! EGR cleaned out, it was totaly choked up with thick black goo, taken for a long road test and drives well with no loss of power or warning lamps etc Forum Master Technician.

HA Incoherent isn't always synonymous with "garbled. Incoherent data could mean that it's reading is beyond the range of plausible relationships with other sensors.

Can you hook a recording scope on it and review after road-test? Posted Thursday, July 09, PM. It has just gone back to the customer, he needs to get back up to Suffolk i am in Surrey tonight so I wont be able to do any tests until next week, Thanks for your input guys, I will post any conclusions, im sure it will run much better with the EGR cleaned out anyway.

Posted Thursday, July 16, AM. Update, Now that the EGR valve has been cleaned up it has been driving the best its has ever done since the guy first got it, the fuel economy is much much better too! Now sounds like you may possibly have a problem with the turbo boost regualtion, and its hitting over-boost levels On a knife edge! Reading This Topic. Powered By InstantForum.
