Ford Ranger / B-Series :: Changing MAF Sensor / High Fuel Pressure
I have a 2009 Ranger 2.3 L manual with about 100000 miles. The engine was bogging down and I just found out that the MAF sensor is bad from testing it. In the process, I measured my fuel pressure to be 73 psi (manual says 60-65 psi). So I have two questions:
a.) Is there any chance of just cleaning the MAF sensor. The sensor has zero volts when running and warm (or .02 v) and barely changes when reving the throttle.
b.) Perhaps then the high fuel pressure is an unrelated issue. Is this so high that I must change the regulator as I have to change the pump as well? Might it be some other issue than the regulator which is what the Hayness manual says?
One theory I had for the high fuel pressure is that the bad MAF was leading to bogging and lean conditions and the computer was running the pump more to compensate but I think the computer might run the pump based on fuel pressure not the o2 sensor.
Ford Ranger / B-Series :: 2002 - Changing Fuel Filter
Where is is my fuel filter and what are the steps to changing it. I have a 2002 Ford Ranger. Also how do you change the flashers, the left blink is really fast but the right blink is fine.

2001 3.0 XLT Ranger 2wd 4 door
Okay getting ready to trade in my Truck. So I removed all the extra things I put on there while I was in college, the amp, fog-lights, and analog oil pressure sensor along with their wiring. It was pretty easy minus removing the oil pressure sending unit part.
I had to unplug the MAF to move the intake out of the way while I was repairing a loose vacuum tank. But I forgot to plug it back in when i closed everything up. I started the truck and drive it about a half mile before I was able to pull over and plug it back in. Truck ran and shifted fine after that, but the CEL came on. P0119 Coolant Temp Signal Intermittent. Guy at Autozone said it was Intake Air Temp Sensor intermittent and I could just replace the part, but they were showing a separate part even though it is built into our MAFs.
So now the CEL is on, can get it to go away. Truck is a little jerky every once in a while, like a misfire, when between 50 and 60. Before all this the CEL was off. Now after I cleaned it up and removed some of the superfluous accessories, I get a CEL. I wanted to trade it in this coming weekend without having to take a loss because of the CEL or spend more money to fix it.
Ford Ranger / B-Series :: 2002 V6 Slightly Over Heated - Oil In Coolant
My 2002 4.0L V6 Ranger, 4x4 overheated *slightly* this past weekend. I added some water and limped it home with a couple stops, trying not to let it get too hot. I since noticed there is oil in the coolant, so jumped to the first non mechanic's assumption the head gasket was bad. I have had (auto) tranny troubles with this truck in the past and started looking inside today and noticed some red fluid under the truck. I think the tranny fluid cools through the main radiator on this one, yes? If so, do I likely have a bad radiator, or is there another likely possibility?
The only wet areas I can find look like where the hard lines come into the right side (looking from the front) back of the rad. If we can determine that, would I need to replace the radiator, or is there any way to plug the tranny lines and run through a separate cooler? I think this also has a tranny, or oil cooler in front of the main radiator but not sure if that is correct, or what exactly that is. This is my daily driver work truck and will bring work to a stop until I can figure it out.
Ford Ranger / B-Series :: 2002 B2300 - Lower Hose That Comes Off Of Coolant Reservoir Leaking
I'm about to tear into a friends 2002 B2300 4 cyl. The lower hose that comes off of the coolant reservoir is leaking in the metal part of the line. Close to where it bolts to the block. At a glance, it looks like I have to pull the whole top of the motor apart to get it off since the line runs around behind the motor. Is there a trick to removing this coolant line without a lot of teardown? I'm not finding it at parts stores so I guess it's a stealership part.

1999 Ranger 4x4 4.0 - P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)
I have replaced the 02 Sensor, Passenger Side (Pre-Cat), with a Motorcraft DY831...
I reset the Check Engine fault codes, and took it out for a 50 mile journey... Check Engine light is back on, with the same exact code... What next?
I understand that it may be a fuse, and/or it may be a short in the wiring... Exactly how to test the wiring from the connector at the 02 Sensor all the way back to wherever I need to test?
I really need detailed directions, like wire colors, voltage required, or ohms, or whatever is included in this process...

View 7 RepliesFord Ranger / B-Series :: 1995 - Changing Tranny Fluid?
. I'm going to FINALLY change the tranny fluid in my 95 Ranger Splash this weekend and need all the feedback I can get! It's a manual trans with miles shy of the 250,000 mark...still on the original stuff!! I'm only the 2nd owner but I bought the truck with just 45,000 miles on her so I'm willing to bet the farm that it's never been changed. It's getting harder to shift from 1st to 2nd and I'm getting a little bit of grinding from 3rd to 4th if I shift too fast. Reading all the threads everywhere online, so many different people have so many different theories from stock Mercon V to MOTOR OIL??? The motor oil thing floored me but I understand the viscosity difference between hydraulic fluid and lubricating oil. figure out what the best thing to replace the original with to prolong the life of this long running wonder vehicle!

Plan on changing my water pump in the next day or two. Truck is a 2000 Ranger, 2.5L with 185,000+ miles. Just wondering if there are any hints/gotcha's that may not be in the manual.
Any advice on bleeding the coolant after I get it back together?

View 4 RepliesFord Ranger / B-Series :: Code 157 For MAF Sensor
So here is what I got. Code 157 maf sensor below minimum voltage. Here is what the truck does. When the MAF is plugged in and I step on it, the truck surges and when it drops below 1k rpm it dies but I can start it back up. If I hold the throttle at 1k it stays alive. When I drive with the MAF unplugged it runs better no surging but it still dies. Here is what I have done. Reset codes no change, put new MAF in no change. I have traced all 4 MAF wires checked continuity from inside of plug to inside of plug.
All wires checked out good. No cuts breaks or anything. I have checked my battery, starter, and alternator ad all check out fine. I read that someone said if the corresponding transistor in the PCM took a dumb then it would cause not enough voltage to get to the plug because the transistor would dump the voltage from the battery leading to the MAF. I thought about running a direct power source from the battery to the voltage side of the MAF with a switch in the truck to just see if that would solve the issue but I don't know if that is possible or smart.

View 8 RepliesFord Ranger / B-Series :: Engine Hesitates - Got 157 And 158 MAF Sensor Fault?
Problem: engine surging/hesitation, from idle to highway speeds. It will start and run fine, just hesitates/surges when gas is applied.
Before I pulled the codes, I tried seafoam in the gas tank, cleaned MAF sensor, cleaned throttle body, checked air filter, changed fuel filter, pulled/cleaned plugs, nothing worked.
Then today I finally used a scanner and pulled codes (my CEL doesn't work) and I got 157 and 158 MAF sensor fault, high and low voltage. I am reading about 6v on the C and D terminals of the MAF, I know that is much higher than normal, but what does that tell me? Why both high and low voltage readings? Just a bad sensor, or wherever that voltage comes from, ECM?
I also pulled 189 HEGO H02S sensor fault, unable to switch/lean during part throttle. What does that mean, just a bad O2 sensor?
Last I pulled a 542, fuel pump secondary circuit fault. Does that mean the fuel pump is bad or going bad?
More importantly, what should I troubleshoot first, would any of these codes cause my problem?

My check engine light came on about a week ago and was unsure what the problem was. So I tested the codes and it said that the camshaft position sensor was bad. So I have tried finding this sensor but little to no luck. I was unsure if it was the 2 or 3 pin, but after looking at some pictures of the engine I'm thinking it is a 2 pin. I attached two pictures of what I think might be the sensor? But I am unsure. This was right next to the timing belt cover, which is where it said it was located. I have a 1996 Ford Ranger, 2.3L.
