Hello, and thanks in advance for any help anyone can give me. I will start out with saying this forum has been very helpful to me in the past but this is my first post. Also I am not a very good mechanic and needing some help. I have A 2000 ranger 3.0 4x4.

****** UPDATE***** I Discovered that Under the hood fuse #13 was blown. Manual says it is for heated oxygen sensor, EGR vacuum reg., EVR solenoid, Camshaft position Sensor, Canister Vent solenoid. When I replace the fuse runs great just like it should. Within a few miles and seems to be when accelerating going up a hill blows again. Can not see any obvious bare wires what does anyone think could be causing it to keep blowing. ***********


Other day I was driving along with everything fine and all at once I lost almost all power no acceleration hardly at all And my check engine light came on. I was close to home so I was able to limp it to the house. Next day I looked at it and it started right up with a slight rough Idle but as soon as I put it into Drive engine was rough and no power at all. RPM would not hardly go up at all. Checked my air filter and did some googling to check a few things but really I was clueless. A friend loaned me A scan tool and I plugged it in this morning. And kinda sad to say I am more lost now than I was after receiving so many codes. The codes are as follows:
P0113 / P0155 / P0141 / P0135 / P1451 / P1000 / P1754 / P0760 / P0755 / P0750 / P0743 / P1747 / P0176
With so many codes making me think I have a major problem I hope I am wrong. I did replace my thermostat about 3 weeks ago it was over heating a little and heater was not working well. Replacing the thermostat fixed that problem. I just wanted to give you as much info as possible. Other than that Issue I really have had no problems with the truck and before I got the truck it belonged to my uncle and he had no real problems with it. Thanks again for any help anyone can give me I really do appreciate it.

 

Yes, those codes are from blown fuse 13, 2000 Ranger

The most common cause is a melted O2 sensor wire, or bad O2 sensor
You have 3 O2 sensors
Each has its own round 4 wire plug on the Truck's Harness, then a 4 wire lead that comes attached to the O2 sensor, that plugs into the truck's harness

O2 sensor looks like this, with its lead: https://m.media-amazon.com/images/I/...1000_QL80_.jpg

Lead can be short or long that's what the different part numbers mean, the O2 itself is the same on all Rangers 1993-2011

Since the leads are always near exhaust pipes.....................one can melt and short out the Heater wires, fuse blows

You have one O2 on each side of the engine just after exhaust manifold, so 2
And then one on passenger side under the truck after the Cat Converters, this one's lead often runs over the top of transmission and connects to the truck harness on drivers side

In any case these codes are all because fuse 13 blew, and they all rely in fuse 13 12volts
P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0155 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0176 Fuel Composition Sensor Circuit Malfunction<<<<assuming you have a Flex Fuel Ranger
All the P7xx codes
P1754 Coast Clutch Solenoid Circuit Error
P1451 Evap Emission Control System Vent Control Circuit

P1000 just means battery was disconnected at some point, probably by you, it will clear itself once fuse 13 is solved

Not caused by fuse 13
P0113 Intake Air Temperature Circuit High Input
Need to wait and see if this one self clears after fixing fuse 13 issue, but didn't cause it


P1747 EPC Solenoid Short Circuit<<<<<<<<<<<<< this one is odd, and could blow fuse 13
Electronic Pressure Control(EPC) is a solenoid inside the transmission

And it is powered by fuse 13 same as the other 5 solenoids in the transmission
But computer didn't set a P07xx code for the EPC solenoid

If there is no obvious damage to the O2 sensor wires I would disconnect the 16 pin transmission connector, drivers side just in front of the shifter

Wiring seen here:


Pins 11 and 12 are connected to the EPC solenoid inside the transmission
Put an OHM Meter on those pins and you should see 3 to 6 ohm, if its under 3 or 0 ohms then a short in the wires inside or the solenoid itself

 

Thank you so much for your help; I had unplugged the oxygen sensor and took for a short drive all was fine.... Then I drove it about 10 miles and truck acted great. Got back in my truck to drive home and blew fuse. I messed with a little and lucky I was at my uncles so he took me home back to the truck this morning and wont start at all. I can not hear my fuel pump kicking on at all. I checked the 30amp fuse and was ok. I tried the relays for the fuel pump with no luck at all. I thank you so much for your past help and it is still a problem. But now a new problem Do I have a really bad short somewhere?

Thanks again

 

Fuse 13 is 15 amp fuse???, if you replaced it with a 30 amp fuse then you probably blew Fuse 8 in the engine fuse box, it powers the 15amp fuse 13

Yes, you have a short but not a direct short or the fuse would blow as soon as it was replaced, or with key on depending on the fuse

 

Thank you I will check that fuse... Yes when it broke down I had some "help" from the neighbors that I didnt really need cause they didn,t really know what they were doing either. I dont know what I am doing and one clueless person was enough. But my "help" did replace that fuse with a 30 amp without me realizing it until yesterday. Until they put that 30 amp in I had only replaced it with a 15 amp fuse and only blew fuse 13 time and time again. I will check that fuse I thought I had pulled them all and checked them but maybe not. Again the wrong kind of help yesterday. At least me and my uncle realize were not sure what to do and just dont go replacing stuff with whatever have. Been trying to do it the correct way for this reason to not add to my problem... Thank you for your help.. I can see from this post and other posts I have refrenced in the past you really know your stuff. Very good of you to help folks the way you do. Gonna check that out. I hate that my truck is not broke down at home. It is safe where it is so thats good but about 20 min Drive.. Do ot get lucky enough to break down at home very often.

 

Since unplugging the 3 O2 sensors didn't help I would pull the transmission's 16 pin plug and test OHMs on EPC pins 11 and 12, since that code was present

 

Will do. I did not get to my truck today. And calling for rain here tomorrow 90% all day. Might be Thursday before I get there. Hope I can get the fuel pump running and truck to start and then will try all of your suggestions.

Thanks

 

You were exactly right. Fuse #8 blew and now power back to my fuel pump and truck starts. I thought I had checked all the fuses well but I guess not. Lesson learned dont rush through it. So now back to my original problem. I am going to look at the 16 pin connector. Is this under truck? I google it and dont really get alot. Or is it inside? Thank you

 

Under the truck on driver's side of transmission, its just in front of the transmission's shifter/DTR switch, seen here: https://www.explorerforum.com/forums...29-jpg.312602/

 

Thank you for the picture. I hate to be so difficult and sound so ignorant about this but I can not find the plug you are referring to. I have looked and I am sure I am just over looking it but I just cant see to locate it. Is it going to be on the bottom the side of the transmission? I am so appreciative of your help and hate to keep being a bother to you but any help you can give me on locating the 16 pin plug will be so helpfull.

 

It the square black thing in the picture with 16 pins inside, in 4x4 arrangement
Look like the diagram in post #2

Yours will have a big wiring harness with connector plugged into it, you need to unplug that connector to get to the pins to test them
No, I do not know how to unplug that connector, looks like tabs on the sides

 

I am sorry it has been so long since I have responded. I had gotten the flu and just had not felt like messing with the truck.. I have found my problem!!! I checked the plug for the transmission like you had suggested and tested good. So I started once again tracing and chasing wires and what a nightmare that is. I decided to remove the bed of the truck and there it was a bright shiny wire staring right at me. Right at the plug for the canister Vent solenoid. I unplugged it and fuse did not blow. I have drove it about 20 miles with no problems. I have been told I can leave that unplugged. My question is what is the downfall to leaving that unplugged? Is it OK or is it a bad Idea? I want to that you for all your help and your knowledge. You have been a huge help to me.

 

Its part of the EVAP system, so won't effect engine or trans operation, or driving

EVAP system uses engine vacuum to pull gasoline fumes from the gas tank so they don't pollute the air
There will be a CODE and CEL(check engine light) will come on
