Ford F-150 - 1997-2003 :: P0136 Code - Horrible Fuel Mileage

2002 F-150 4x4 super crew w/5.4..So I've got the P0136 code, horrible fuel mileage (around 7 mpg just driving to work without hitting very many lights) and the check engine light comes on intermittently, and I get that code. I have borrowed my friends scanner ("Determionator Scan System") and I can see the live data from the 02 sensors. Today I drove around for a while and watched the scanner and the H02 data, and the downstream sensor on bank 1 shows at most, .09 volts, and it also says its detecting a lean mixture. The code P0136 is for this sensor in particular, and I have heard that an 02 sensor should be around 1 volt. The downstream sensor on the drivers side showed around .75 volts at max.

I believe that it is working correctly, or close to it, and I do not get a code for that sensor. So my question is, is the downstream sensor on the passenger side (bank 1) causing the P0136 code and the poor fuel mileage? also, could an exhaust leak cause the sensor to throw a code and not be bad at all? I do have some very minor exhaust leaks, on both sides of the truck..I'm leaning towards replacing that one 02 sensor. The wires and plug connection to that sensor look fine, plus I would think that if there was a bad wire/connection it would not register any voltage at all.. I have to add, the truck runs fine overall after I replaced the intake manifolds last week. It does still idle high, around 1,000 rpm, after coasting to a stop, then after a few seconds goes back down to a normal idle of around 650 rpm. but idles normal upon starting or in park.

Ford Escape / Hybrid :: 2004 XLT - CEL Popped Up For P0136 / O2 Sensor Code

2004 XLT 3.0L 141K

I just bought the truck on Monday, the CEL popped up on Tues. It shows code 0136. No other codes. CAT "not ready" on scan tool

A google search proved this is a common topic that for some owners is a repeating and cronic sort of issue. What I've read online is that there is an assortment of things that can cause this O2 sensor to throw this code:

Actual bad O2 sensor
Faulty wiring or connection
Misfire throwing mix off
bad convertor

I don't believe this list covers all the accounts I read but these I have were definitely repeat offenders. My intention is to take to a dealer and let them have first crack at sorting it out. I'm handy enough but I see this as something where an unseen detail can drive ya crazy.

Ford F-150 - 1997-2003 :: Codes P1518 / P0316 / P0303 And P0136?

I have a 2003 F150 V6 4.2L, 171,000 miles on it. I have four codes on it.

#p1518
#p0316
#p0303
#p0136

I had a p1518 in november of 2012, had it repaired and its back. In the time that I had it repaired and it came back on (maybe a month and a half ago) I only drove the truck maybe 3000 miles, if that. Just curious if this particular part should have some kind of warranty either by the MFG or dealer since the dealer repaired it. Have a limited budget, trying to find out what I can fix on my own in a timely manner.

Ford F-150 - 1997-2003 :: 1999 - Code P0500 - Speed Sensor Has Been Broken Off

So I'm getting code p0500 the question I have is will the speed sensor on the tail on my transmission cause this code on my 99 f150 4x4 . the reason I ask is because this sensor has been broken off . I'm hopeful it only control's my speedometer and is not related to the code . I've tried to remove what is left however in fear if I get it loose it may fall into the transmission. I will be replacing the speed sensor on the pumpkin this weekend . but the transmission it's the upper one is broke off below the surface of the transmission this is a manual transmission....

Ford F-150 - 1997-2003 :: 2000 - Wired Chewed Up - CEL With Code P1744?

I have a 2000 expedition with the 5.4L and a squirrel got under the hood and chewed up some wires that run to the pcm along with some vacuum lines. I got all the wires I seen spliced back together. I drove it yesterday for the first time and my check engine light came on. I pulled a p1744 a trans solenoid for torque converter lock up. The fluid isn't low and looks bright red on dipstick. It drives and shifts fine. Is there a certain wire from the pcm harness I need to look at first?

Ford F-150 - 1997-2003 :: 2000 - Code P0705 - O/D Light Flashing?

To start I was driving to work tonight and noticed the o/d "off" light flashing. it shifted hard one time then felt normal the rest of the way to work. At red lights the o/d light world turn off and about 3 minutes later it would flash again. When I got to work, I checked my code reader which gave me the p0705. I have searched around the net for about an hour and one thing i am seeing is that the fluid is "hot" or that there isn't enough. i have checked it and it looks slightly low like right above the add indication.

The only sound I here from under the truck is a rattle when in drive and at idle, but once I give it some gas it goes away. On they way home that night the o/d light was still flashing but it drove fine just at higher rpm, it down shifted hard one time but there were no other issues. I checked the fuses and they are all good.

Ford F-150 - 1997-2003 :: 2000 - ABS Light Comes On A Few Minutes After Driving But No Code

2000 F-150 Triton V-8, Super Cab, 2WD, ~170,000 miles, 4-wheel ABS (one speed sensor on each front wheel and one on the rear differential). The ABS light comes on a few minutes after driving. It seems to take a little bit longer for the light to come on when the weather is colder.

I used a Cen-Tech 60794 OBD II/CAN with ABS scan tool with key on, engine off, and the below sequence. No codes were detected. I then left the scanner connected but powered off and drove around until the ABS light came on. Pulled into a parking lot with engine running, powered up the scan tool and went through the following menu choices:

Diagnostics
ABS
Area - USA vehicles
Model - Ford

Although the tool's instruction manual has several more items that may or may not be required (VIN digits, model year, etc), the next thing I saw is a message indicating the scanner is linking with the vehicle computer. During that time the ABS light went out. Next on the scan tool display my choice was to read codes or erase codes. I selected "Read codes" and the display said there are no codes in the module.
