20 Most Recent 2006 Ford F-150 Questions & Answers

Does this include the CHMSL ( Center High Mount Stop Lamp ) ?
The turn signals work fine when you say all other lights work ?

If so could be 2 things.
1. The BPP ( Brake Pedal Position ) Switch
1.1. The BPP has 4 wires on it
1.1.1. Tan w/ Red stripe & Pink w/ Light Green stripe are the shift interlock
1.1.2. Light Green w/ red stripe & Light Green wires are the Brake lamp part of the BPP.


When you have the brake off, the Light Green w/ Red stripe wire should have power on it ( from fuse #2 ) and when you press on the brake pedal, the Light green wire should also have power.
- If only the Light green w/ red stripe wire has power with the brake on and off, and the Light green wire never has power, the BPP switch needs to be replaced.
- If the Light Green wire does not have power ( and you are use of the ground you are testing with ) fuse #2 is blown.

- The fuse for the brake lamps ( Fuse #2 in the cab fuse panel ).
-- This is if the CHMSL is also not functioning

MAP (manifold absolute pressure) vs MAF (mass air flow) https://www.google.com/search?q=2006+Ford+F-150+4.6%2C+2+valve.+Why+doesn%27t+it+have+a+MAP+sensor. ..

Try your boo(brake on/off switch) switch on brake pedal. unplug it and jump connector with a piece of wire and have someone look behind truck and see if brake lights turn on. if brake light illum,there you go replace switch. make sure pay special attn how switch comes off after pulling pin out. also try fuse if all else is ok.

This sounds like the brake light switch or the control switch on the brake pedal is bad or loose. Check under the dash above the brake pedal there should be one or two switches that tell the brake lights to come on and the cruise control to shut down.

Question edited for clarity, maker name and first in question. Question moved to sub category. Much depends on whether it is a manual or automatic, but in general, yes, reverse is a single speed, slow speed, high torque drive in a rearward direction. Reverse gear issues in the link. https://www.google.com/search?q=2006+Ford+F-150.+Is+reverse+separate+from+all+other+gears ..

Scan for Diagnostic Trouble codes. Put it on a Pro Grade scan tool computer and check Live Data at the time it fails. Check fuel pressure, especially as the control module was causing issues. The electronics will tell you the reason.

You'll need a scan tool that can read transmission codes.That will get you started once you retrieve the code.

Do you have a 2006 or 2007/08 F-150 ?

The problem section is for the 2006, which 37 & 39 are the correct fuses.

Change in the 07-08 MY for the power point fuses

Instrument Power point is fuse #117
Rear Power Point and Center console power point are fuse # 37

Fuse #18 & Fuse #20 are for the overhead power point, one is hot in run / start ( Fuse 18 ) the other is hot all the time ( Fuse 20 )

Sound like a wire loose. could be the earth cable to the engine, or the main power cable from the battery to the fuse box/ignition switch/starter.

Probably a vehicle speed sensor failure or loose connection/broken wire.

They are a pain in the rear. On either side about one foot in on the bottom get somethings like a long prybar and lift up on the seat cushion. Then get a light and look for a skinny hook on each side. There is a metal tube they hook to. Get another prybar and push the hook towards the back of the truck and lift upwards at the same time. They are hard to see. Good luck

i don't know. sounds to me like a dead / loose light.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help thanks

Check to be sure if the vacuum is connected from the engine to the shifter switch is connected and that you're getting vacuum from the switch to the front differential. No vacuum to the differential diaphragm, no 4x4 front action.

run the fault codes first could be a leak back problem from a faulty pressure regulator

Hope we're talking about the same thing. The text is a little small, hope you can read it or if you put mouse arrow on it, maybe it will enlarge.
