2003 Ford Ranger Problems

Engine -- Verified

The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

Engine -- Verified

The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

Engine -- Verified

The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.

Engine -- Verified

A buzzing type noise may be noted from upper engine area at about 1900 RPM, under light acceleration. Our technicians tell us this can be caused by loose ignition coil bracket bolts. Coil bracket bolts should be checked for the correct torque before further diagnoses is performed.

2003 Ford Ranger Reviews

I HAVE ONLY 48,500 MILES ON MY 2003 RANGER XLT AND I HAVE HAD TO REPLACE CAD.CONVERTER AND NOW UPPER AND LOWER BALL JOINTS. I THINK FORD DID NOT HAVE A GOOD IDEA WITH THIS TRUCK. BALL JOINTS SHOULD LAST 100,000 MILES AND CAD. CONVERTER FOR EVER. I WILL DRIVE HER TILL SHE FALLS APART AND AFTER THAT I AM A CHEVY MAN

This truck has had a transmission leak at 22,000 miles and an oil leak now at 53,000 miles. The brakes are terrible especially the rear. They tend to lock up when cold and wet. I have the 3.0 6 cly and the gas milage is awful. This will be my first and last Ford truck.

For 3.0 engines replace the camshaft position sensor [Part Number: 6B288 (DU-81)] and camshaft camshaft synchronizer [Part Number: DA-2089] every 75K to 90K. This is basic preventative maintenance since these parts are known to go out at that range. If you neglect to do so it will destroy the engine when it fails.

I've been given my 03' Ford Ranger for my graduation present, and because I wrecked it once... This truck rules! whether it be recreation, business, or even the common race "caugh", my Ford Ranger has survived! Though an engine squeak or holler here and there. It gets whatever the job is done.

Great Truck! I even fixed some things the wrong way and the truck runs like a champ. Easy to work on, cheap parts! Great economical Truck with good reliability.
