Code E85 is the same as P085 which is a problem with the throttle position sensor.
The sensor would need to be tested.

    The TPS is mounted on the side of the throttle body. The price would depend on your area.

E85 stalls when starting Z4 in cold weather


This is common with E85 Alcohol has a lower vapor pressure than gasoline and in the cold weather it does not like to ignite. If you don't have an E85 compliant car then you need to have the ecm programming changed. If you do have an E85 then the injectors may be dirty. Also E85 picks up a lot of moisture so that may be a problem too.

Can I run ethynol (e85) fuel in my 1998 grand voyager. Have always used unleaded 89 octane. Has 200,00 miles.


98 was the first year chrysler introduced an E85 compliant minivan. This only applies to the 3.3 liter engine. The 3.8 liter is NOT compatible.

We have a 99 and this is what we found. It ends up costing us more to run E85 than regular fuel. E85 is less efficient and will decrease your fuel economy 25-30%. Currently the price offset does compensate for this and as a result you will fill up more often and will not see a significant savings after the math is done.

Chrysler also recommended, at the time, to use a special E85 compliant oil which also costs more money. You can check with your local chrysler dealer to see if this is still true.

I thought my 2008 Escape 2.3L 4cyl could run on E85, but when I got through the 1st 1/4 tank, my ck eng lite came on. Is this a result of the fuel or something else?


I don't think any of fords four cylinders are e85 compliant. The escape 3.0 liter didn't become e85 compliant until 2010 if you vehicle was e85 compliant it would have a flex fuel emblem on the side of it and it would have a sticker on the fuel door. Your check engine light is most likely because of the e85. If it's running ok. Burn of that tank and then return to regular gas. The check engine light should go out after a couple of fill ups.

Is E85 safe to use in the 2002 Dodge Grand Caravan Sport?


If your vehicle is equipped with a Flex-Fuel engine it is safe to use E85. If your vehicle is not equipped with a Flex Fuel engine, E85 will cause all kinds of driveability problems including a no-start. The vehicle should say "Flex-Fuel" on it or there will be a green "Leaf" emblem somewhere on the body.
For a 2002 Dodge Caravan, the best way to positively identify the engine is to look at the VIN. The only engine code that is Flex-Fuel is engine code "G". The engine code is the 8th digit of the VIN. The 10th digit is the year of manufacture and should be a "2" on your vehicle. If there is ANY OTHER engine code, DO NOT put E85 in the tank.

I used e85 gasoline instead of regular fuel. would that damage my car. It is a 2009 yaris


Dear Madam or Sir,

no, it will not damage your car but you will encounter problems with starting from cold temperatures and a lack of power running your Yaris on E85 without an extra e85 control unit.

The reason is, that the fuel management system of your car can´t compensate the different properties of E85.
But no worries.
I suggest to refuel with regular petrol when your tank gauge has reached 50 % , you should be fine with that.


Kind regards from Germany

E85 Ethanol effects


E85 needs special fuel lines and and all rubber/plastic seals and o-rings must be replaced with versions which are E85 compliant. The ignition timing needs to be altered (easy) as does the ignition advance curve (likely difficult). You may also need a different grade of spark plug and possible changes to the carb jetting (very difficult to get right without access to a dynamometer equipped rolling road).

In short, unless you're having a major rebuild incorporating E85 from the outset and you're happy to experiment with various settings then avoid using E85 altogether as it can cause significant damage. On vehicles certified for use with E85 it's no problem at all.

If your vehicle can use E85 there is usually a lable on the gas cap or near it that says you can. If no lable is in view then most likely you cannot use E85.
