[glackey88]

hello,i have a 01 ranger with the 3.0 in it,replaced,fuel flter,vacuum lines,egr valve,all 3 02sensors,had hooked up to scanner and it told me dpfe sensor issue.so i tested dpfe sensor and found it bad.replaced dpfe sensor drove truck to work and then home and check engine light came on again and im getting 100 miles out of 1/2 tank of gas.can someone help with is issue,its driving me crazy.t/y

Could be plenty of reasons. Can you tell us what codes the Check Engine Light is giving? Is it the same code or are you assuming it is?

Ok, whats with this? He asked a question, which im going to ask as well. You said your CEL came back on, what was the code this time?

Seriously, glacky, clam down. That wasn't meant to be a dick response. There is a lot that goes into fuel economy. The more information you give us the better response we can give you. If your cel is on we need the code it's throwing

im calm just did not like the middle finger thing im sorry for getting rude.the codes i get from scanners at discout suto and autozone say codes1152 and 1132 which is saying something about upstream something in bank2 running rich,i replaced all 3 02 which probaly were not bad if reading rich.my friend hooked his snap-on computer to my truck and it told me about dpfe sensor which i never heard of,so tested it and it was bad replaced,drove truck 16miles to work no cel,drove truck home light kicked on again and truck burning gas.

 

[glackey88]

im not here to make enemys, im here to get and help whoever i can if possible.sorry if i offended anyone

The middle finger is in his signature, the signature starts under the line..it always comes up after whatever you post and isn't directed at anyone, its just there to give info/quotes, whatever. So the stuff under the line isn't directed at you at all.

First of all, it sounds like you're calculating your fuel economy the wrong way. What the gas gauge says is not important. It is a representation, and is not always accurate.
Here's how it should be done:
1. Go to the gas station and fill up the tank.
2. Note the mileage, or set your trip odometer to 0.
3. The next time you need gas, full up again, and note the mileage since the first fill up.
4. Divide the number of miles you put on the truck between the 2 fill ups by the number of gallons it took to fill the tank the second time.

That is the only way to obtain true Miles per Gallon. Do that, then tell us what you get for your calculated mpg.
Most trucks get between 15 and 20 miles per gallon depending on the truck specs, your driving style, the type and quality of fuel you're using, the terrain you drive on, etc. There are TONS of factors at play. Get your MPG figured out, and give us some more info about your situation and truck and we'll try and help you figure out if something is wrong.

hello drove truck to work this morning and had my buddy hook computer up,im getting codes 1132 and 1152 off his snap-on scanner when check engine light was on.he resetted my computer i drove truck home and no engine light.but if light comes on again and show same codes,what do you think could be problem other than i know im runnibg rich

 

[glackey88]

st. mitch i understand what you are saying to see what kind of fuel milage im getting,but can you help me telling why check engine light comes on and the same codes keep popping up.codes 1132 and 1152 on my friends scanner.when i used autozone and discount auto scanner it did not mention dpfe sensor,my friends snap on scannner found that code.but all 3 scanners keep giving me the same 2 codes.dont understand this part of it

You replaced the sensors but did you do a good check of the wires? Looking for and chaffing or braked in the line? Also the dpfe sensor could be causing all your problems. On my 2.3 it is on the fire wall just to the passengers side of center. It's a little silver box that's about the size of a pack of cigarettes.
It has two vacuum lines coming off of it and they tie into the exhaust manifold and a single electrical connection.
Check the vacuum lines for deterioration.
What that sensor does is act like a mass air flow for your exhaust and it factors into your egr opening and closing. If its faulty it could be why it's sensing a rich condition.

wr250rdr i replaced dpfe sensor and the 2 vacuum lines to exhaust and intake manifolds,also checked all wiring no melted or chaffing on any of them.i did take zip ties and zip tied all wires away from exhaust manifolds and took a can of air and blew out the harnesses for 02 sensors cause i heard if the connectors are dirty could give a false reading.

 

[wr250rdr]

Do you still have the codes? Also did you clear the codes after you pulled them?

 

[wr250rdr]

Also did you personally replace the o2 sensors? The up Stream is different from the down. They measure different things and I wouldn't be surprised if someone at az gave you the wrong part. Is your exhaust black and does it smell like fuel?
