Hello, like the title says I have a code p017900 which has something to do with the fuel quality sensor, or fuel composition sensor in some locations. I have not been able to find any information as to where this is located. Does anyone know? Thank you so much!
I saw a video about a c350 on youtube it showed where the sensor goes through the foot well on the drivers side but I couldn't even find the fuel lines on the drivers side when I pulled the plastic off and the sensor wasn't there. I pulled the passenger side off and still could not find the fuel lines. I assume they go under the metal plate that is under the plastic cover.
I dont have flex fuel so im not familiar with any of the parts. I dont think ive even seen the fuel line under my car before though never had the side undertrays off.
Looking at the parts diagram for your 204.080 I dont see that sensor listed. It does mention an ethanol sensor adapter.
I still havent come up with any useful info on that sensor. But in the manuals it shows the fuel lines.
In the photo below you can see the brake lines coming from the rear of the car (red line). So the fuel line should run closer to the middle towards the drive shaft. I would think in a flex fuel model the sensor should be in that area.
