Ford Ranger Misfire Codes

You’re not going to be a happy camper when you’re done reading this post. Ford has issued a TSB #05-26-3 that describes a fairly significant design problem with the cylinder heads on 2004-06 Rangers with the 3.0 overhead valve “Vulcan” engine. The problem shows up as any of these misfire codes P0300, P0301, P0302, P0303, P0304, P0305, P0306, and P0316. The TSB states that the cause may be an exhaust valve “recession” that causes a loss of compression. Ford wants you to do a running compression test and a cylinder leakdown test. Click here to see how that’s done. If the results show low compression, the only fix is to replace BOTH cylinder heads with the new redesigned heads now available from Ford. The repair costs may be covered by your warranty. Check with the dealer to make sure. This is a costly repair.

Ford door switches—a known problem

Rick — Wed, 02 Apr 2008 03:21:00 +0000

Remember the pin/plunger switches that car makers used to install in the door jamb? Well, you won’t find them in Fords—some brilliant engineer had a “better idea.” They decided to place the switches inside the door right under the latch mechanism. When the door latches, a lever deactivates the switch and the body control module turns off the interior lights. Good so far….. The problem is that the switches gum up with grease from the latch mechanism or corrosion. That’s when interior lights stay on.

Some shops have reported success by saturating the latch mechanism with a rust penetrant and opening and closing the door about 20 or 30 times. That works the penetrant into the mechanism and some of it finds its way to the lever and switch. You really don’t have much to lose by trying this method because the only alternative is to remove the door trim panel and replace the switch.

I’ve tried this on a few Ford vehicles and had success. However, it’s not a long term fix. You will have to do it about twice a year.

Check Engine and Seat Belt Light on, dead battery – Ford Ranger

Rick — Thu, 14 Feb 2008 01:13:00 +0000

If you own a 2005 Ford Ranger and the battery goes dead, with the check engine light on and the seat belt light on when the key is NOT in the ignition, check for corrosion at the back of the fuse box for fuses #11 and #15. If you find any, disconnect the battery and clean the fuse box with electrical contact cleaner. Allow the spray cleaner to dry completely. Apply a small dab of dielectric grease to the area to cut down on corrosion. Then reinstall the fuses, reconnect the battery and charge it before starting.

P0443, P1443, P1444, P1445 on Ford Ranger, EVAP codes

Rick — Wed, 06 Feb 2008 04:47:00 +0000

For a P1433 code, check for loose, broken, kinked, or disconnected fuel vapor return hoses. Check the wiring harness issues discussed above.

For a P1444 code, check the purge flow sensor connector. You may find a broken VPWR pin, or it may be damaged. Also check for a possible purge flow sensor harness signal that may be shorted to power ground. Finally, check for damaged wiring as described above.

For a P1445 code, check possible purge flow sensor harness signal or ground wire/pin that may be open or broken. Check for damaged wiring as described above.

The actual TSB shows a re-routing diagram that moves the wiring harness away from the power steering pump assembly. If any of the terminals show the conditions listed above, purchase a Ford service kit #F67Z-14289CA and follow the procedure listed in the instruction sheet to repair the connector.

If you are still getting the codes, conduct all the electrical tests listed in the TSB. (It’s too long and involved to list here). If everything still checks out but you’ve got the same codes, replace the purge flow sensor and solenoid assembly.

Wipers won’t shut off — Ford – The problem and the fix.

Rick — Mon, 09 Jul 2007 00:53:00 +0000

If you own one of the Ford vehicles listed below and you can’t get your wipers to shut off, here’s the fix. Ford wiper systems are controlled by the turn signal stalk on the “multi-function” switch. As you rotate the knob to activate the wipers, the resistance changes and the Wiper Control Module (WCM) reads the changing voltage and commands the wipers to a new speed or on/off. The problem of perpetual wipers is due to a poorly designed multi-function switch, not a bad WCM or a defective Generic Electronic Module (GEM). Ford has changed the part to correct the problem and now has a newer multi function switch. Before changing out the switch, make sure all the connections from the switch to the GEM and WCM module are fully seated. If they are, you will need to install the newer switch. Make sure you disable the air bag system before disassembling the cowling around the switch. An electrical mishap while working on the switch could pop off the air bag. The affected vehicles are:

1999 Taurus • 1999–2000 Mustang, Explorer, F150, F250, Ranger and Windstar •
2000 Excursion • 1999 Sable • 1999–2000 Mountainee
