307 malfunction P0171

1.6 307 owner (my first vehicle) When I bought the vehicle, the first thing I did was to have the xxxx lpg system installed (I wish I did not get it). I traveled 20,000 km, and in the meantime, the coil jumped 1-2 times. 3-4 days ago the coil was completely canceled and the malfunction lamp came on. We have connected to the computer - Crank speed sensor - 0171 poor mixture - Coil failure 1-3 etc. The most obvious malfunction was the coil at that moment. We erased the faults 20-30 who then turned on the lamp again: -Crank speed sensor -0171 poor mixture My master checked the crank speed sensor, determined that he had moved, removed, cleaned and installed it beautifully. After 20-30 km we cleared the faults, the fault lamp came on again: -0171 poor mixture (system 1) My master stated that this error is generally related to the lpg setting, but it may also be caused by the oxygen sensor. He told me to make a tube adjustment and to use the vehicle with gasoline until I made the adjustment. I used the vehicle 20-30 km with gasoline and the malfunction lamp came on again.We connected it to the computer: -P0171 poor mixture (system 1) oxygen sensor values were checked from the computer. Serial ups and downs were observed between min 197 max 1000 values. No malfunction was detected in the computer, but just in case the oxygen probe was ordered. I used 1-2 vehicles with gasoline, then we tried the new oxygen sensor, but unfortunately we found that the fault was not caused by it. Although the vehicle was used with gasoline, this was causing the malfunction, so we continued to set the gas setting aside and investigate the cause of the malfunction. Excerpt: According to the reading of the temperature sensor, the ECU was adjusting the air-fuel mixture, it was RICH by spraying plenty of fuel when the value was low, and FAKIR mixing by spraying less fuel when the value was high. Based on this information, we checked the temperature sensor's values. We could not detect a malfunction in the temperature sensor either, and the value in the vehicle coincided with the value on the pc. 98 degrees fan worked 92 also stopped etc etc .. My master said that even if lpg is not used, it may affect the system because it is installed in the vehicle. He told me to make the gas adjustment and maintenance and use the vehicle a little like that. I will go tomorrow and have the gas adjustment and the cylinder maintained. But I think the problem will not be solved in general ... P0171 has been discussed in many forums but it has not been resolved for a long time. I have been researching for a long time. Everyone has linked this problem to the gas setting, but I think the reason for this error is not the gas setting. If the gas setting does not sit, it should be 2-3 if it is not at the 1st place. There are necessarily those related to gas adjustment, but the problem of friends who cannot solve this problem is not gas adjustment. I am a forum user (sharing information receiving information) I am a new member of this forum for the first time, I am writing about a car related topic. You can be sure to share all the positive and negative developments here. There is no problem going on my car's traction. It is also very smooth to work in idling. There is only one problem that I feel visibly, the room stumbles a little when first running in the morning, but it also gets 1st, but it was better before the faults occurred. As I see this malfunction lamp, I get cold from my car. I thank all the friends who have helped in advance. What's wrong with my car? What should I do? ttaylanaa2012-08-23 23:20:37

You should get used to using the LPG 307, which has the fault code and the lamp is lit, because the number of 307 with LPG and that lamp is not lit does not exceed the finger of one hand.

I have used more than 100 km of vehicles in petrol, is it still caused by LPG without passing it to LPG? & nbsp; If necessary, I can completely disable the lpg system and test the vehicle. ttaylanaa 2012-05-15 11:38:06

my 2006 307 xt premium 1.6 car has BRC lpg for 3 years A2 engineering in brc authorized services have been installing lpg so that the fault lamp does not light up and it was as promised that the fault lamp did not light up and I am satisfied with the performance & nbsp;

As a person who has been happy for months with the same error, I am happy with the engine warning light that goes on after 20-30 km after LPG is set and continues after regeneration and turns off again if you switch to LPG again. There are two reasons for this, the first one is that the LPG brain is copying the engine brain exactly to itself and it gets these values directly from it. The easiest way to understand this is to hit the middle silencer and check if there is a click on it. My vehicle also has the Atiker sequential system LPG and although I showed it to many services, the situation was always the same with you. When I found out that he was the authorized service of the atiker, I explained the situation and told me to bring the car.I brought the car quickly and adjusted it for about 1 hour, and he told me to let me know when the engine warning lamp went off towards the end of the adjustment. Then the beep sound and the engine warning lamp went out in front of my eyes, and I have not witnessed that light burned in LPG or Benz that day. The diagnostic light that turns on even after km will turn off again after 50 km. The only reason for this is the pressure difference between the combustion temperatures of Gasoline and LPG. By the way, I think the same engine with 206 is 1.6 16v 110 hp. I hope it is a problem with my experience.

Although I used it in gasoline, it was very boring to get this error. But if you have encountered such a situation, it is likely that the same situation will happen to me. The LPG brain is copying the engine brain exactly to itself and gets these values directly from it. ttaylanaa 2012-05-15 11:40:56

& nbsp; We just made the tube setting. we went for the test drive 15-20 km road was made even over 170 km / h and there was no problem. . But I was not able to rejoice any more, after 20-30 km I am afraid to encounter the same mistake. I will be relieved if the malfunction lamp does not turn on until the end of this week. I will try to add them here as soon as I can. In a way that friends who are missing technical issues like me can understand. & Nbsp; & nbsp;

& nbsp;

I will not give brands, get LPG from a known place, if possible, always from the same station and even from the same pump.

I searched, and I have not seen anyone associating this problem with the gas received. Thank you for your interest. I did a research on the causes of P0171 failure. When my problem is fully resolved, I will edit it on the page where I opened the first topic. If there is incorrect information, please specify. P0171 error due to gas adjustment (most common)

Do not worry about this malfunction. If you do not want to turn off the lamp until the replacement of the sensor in the lamp, but nobody wants to turn off the lamp, if the car does not want it. Don't worry too much to fix this malfunction.

I turn off the malfunction lamp absolutely, and I guarantee that it will never burn :)

However, this application is also risky, in any other malfunction in the vehicle, this lamp no longer lights.

It seems like a fool to solve a problem.

& nbsp; Unfortunately, after traveling 15 km in the morning, I turned on the malfunction lamp again. U> 2nd reason is that the catalytic convector may either be dissipating or dispersed. ttaylanaa 2012-05-16 10:07:01

[QUOTE = ttaylanaa] & nbsp; Unfortunately, after traveling 15 km in the morning, I turned on the fault lamp again .monur friend: the second reason is that the catalytic convector may either be dispersing or dispersed. I will finally check it and make sure that the fault is 100%.

[QUOTE = text] [QUOTE = ttaylanaa] Unfortunately, after traveling 15 km in the morning, I turned on the malfunction lamp again. I'll make sure it's from the setting. When I was idle, the master tool, which made my last gas adjustment, I heard that it had to be adjusted in motion. There was no problem that we tested later, but ... If I disassemble the lpg system completely, if my problem is caused by lpg, will this malfunction lamp go out? Thanks to the friends who are interested ... [/ QUOTE] The best setting is the setting made by holding the foot at 3000 rpm by pressing the gas from inside. The lamp goes off in calm use as it is adjusted in the rolentide, but it lights up in serial use. Due to the fact that lpgnin sends less fuel than normal while driving at high speed, the air mixture is not good and the fault lamp is lit by the oxygen sensor. [/ QUOTE] It never burns in my car. Since the zavoli service here does not trust me, I will not make any more adjustments. I will go to the authorized peugeot service as soon as possible and ask for the fault to be remedied. If they tell me there is a problem caused by lpg, I will ask them to report this fault and go to the zavoli authorized service with the report I have. If my problem is not solved, I will apply for consumer rights.

[QUOTE = laedri] I don't think this fault is too much trouble. If the car does not want to turn off the lamp until the search for a solution goes to replace the lamp, if the car does not want to turn off the lamp itself. "# ff0000"> If the vehicle does not vibrate at idle, , if the vehicle does not kick when driving at a constant speed, I think don't go too far to fix this fault (!) The reason for telling you to be rigorous in choosing a lpg station and brand. If you find the most suitable lpg for your car, if you do not give up on it, the malfunction lamp may turn off by itself after a while.
