Anybody else ever run into a p0169 Incorrect Fuel Composition error code? I was driving into work this morning and I got a "Special Modes Unavailable" and the car felt like it wasn't getting power to the back tires. It was running a little rough when I pulled over but after I shutdown and started back up she smoothed right out. I did have it happen 1 more time driving into work and when I ran the code, I got a p0169 Incorrect Fuel Composition. Anybody else experience this issue? 2014 base V6 with VAP Tune and Crank shaft fully upgrade.
Thanks!

 

Ethanol contamination, have you just filled up by any chance?

 

I filled up on Friday and didn't drive much since then. I was thinking something along those lines but wanted to see if anybody else had seen a similar issues. Searching for the error code doesn't bring up much.

 

'Searching for the error code doesn't bring up much'

Dont know where you looked but it came straight up for mewww.obd-codes.com/p0169

 

P0169 does not appear in the list of Jaguar codes for the X-Type. You have an F-Type. Best to post in that forum about this issue. Totally different engine, drivetrain, car...........

 

Realized that after I posted that I had the wrong group and I couldn't delete the post... not enough coffee this morning

 

A p0169 code is a po169 code regardless , still the same meaning, still the same cause

 

A stored code P0169, means that the powertrain control module (PCM) has detected a voltage signal from the fuel composition sensor/fuel temperature sensor that indicates an abnormally high level of contaminants or ethanol in the fuel supply. Since flex fuel vehicles can function normally even with high concentrations of ethanol, unacceptable levels of ethanol would likely exceed eighty-five-percent.

Doesn't matter model number

As fuel passes through the inline sensor, it is electronically analyzed to determine the degree of ethanol, water, and unknown contaminants (non-fuel) found therein. The fuel composition sensor not only analyzes fuel composition but also fuel temperature. The information is input to the PCM as an electrical signal that reflects not only what contaminants are present (and to what degree the fuel has been contaminated) but also the temperature of the fuel. Fuel contamination is analyzed, according to the ratio of contaminants to fuel. This generates a voltage signature in the fuel composition/temperature sensor which is input to the PCM as square waveforms of voltage. Waveform patterns vary in frequency contingent to the degree of contamination found in the fuel. The closer the waveform frequency, the greater the degree of fuel contamination; this constitutes the vertical portion of the waveform. The fuel composition sensor analyzes the amount of ethanol present in fuel independently of other contaminants.

 

Is that something that an X-Type can monitor and show as a code? Reason I ask is that in the In the Jaguar list of DTC Powertarin Summaries it does not even show a P0169 code. It goes from P0160 right to P0171. Is that because the X-Type is so old or is there another reason? Just curious.

 

I seriously doubt the X is that sophisticated sorry. That is some deep analysis going on there.

 

Thats the first time ive seen anyone seem concerned about a code they are not getting!

 

Maybe posting in the right forum would help.

 

Not really in this case, a code is a code regardless of the car, the OP did state the car in the title

 

Yes but people in the right forum may have advice about a code that CAN occur on the car.

 

I would have to disagree because the X-Type cannot even monitor that code, so unless a member of this forum would happen to have some prior experience with that code the original poster has a much lower chance of getting any useful responses. If it is posted in the F-Type forum chances are someone could better help with it and share from personal experience.

 

Like I said , a code is a code, P0169 is fuel contamination regardless of make /model/ whatever. I don't even have an F type or x type but I managed to figure it out. Personal experience doesn't even come into it with this fault as I've managed to prove.

 

I am not talking about the code itself. I am just talking about the likelyhood of someone even seeing the post and caring enough to even comment. I would venture to guess most people that are on forums check into only the forum of the car they own or might be looking to buy or in Thermo's case, he used to own and X-Type and now owns an XJ and he thnakfully still hangs around here. If someone on here sees a post about an F-Type and a code number that isn't familiar chances are they won't comment other than to point out that the poster is in the wrong forum. Happens frequently, especially with new members where you have all these different models; X-TYPE, F TYPE, XJ, XK, etc. And usually when redirected, the original poster goes to the proper forum and you never hear from them again in this forum. Now if that same post is in the F-Type section, the odds are much greater of getting help or a reply.

 

The X-type code is capable of displaying it, but the sensor arrangement has a microprocessor of its own, and I can't imagine how you'd add it to a useful display. If you retrofit the system, it would send it to the reader, though.


I don't even want to know what the hardware would cost!


I messed around with a lot of the Jag code (it is just a custom set of the 9141 code), and all of the Ford and Toyota protocols are in there, they simply comment out the ones that they don't need and add their own descriptors (test) to "marque specific" ones.
