The counterman read the check engine codes at my Advance Store in Aylett, Virginia. As always, service quality was top notch. All of the codes pointed toward a problem with my throttle position sensor. I have a 2005 Ford Mustang 4.6 V8. Factory Throttle Position Sensor (TPS) problems are common to this car. Advance had the EC3337 in stock, so I purchased it. Paper directions come with the EC3337 TPS and match the directions in the factory shop manual. The first thing I noticed was that in the TPS, the slot for the tang at the end of the shaft on which the throttle blades rotate was not properly indexed. I had to slide the sensor part way onto the shaft and then turn the sensor to get the holes for the mounting screws to line up. I did that and torqued the screws at 27 inch pounds. After reconnecting the electrical connector at the TPS and the negative battery cable, I started the car. The check engine light came on immediately and the car went into Failsafe mode. "Failsafe mode" appeared in the dash. The car had no throttle response. I turned off the car. Although the directions didn't require it, I tried pushing the pedal slowly down for 10 seconds and releasing for 10 seconds to see if the PCM could learn the new TPS. On restart, I still had all the same problems. I took the TPS back. The Advance store ordered a second EC3337 which came in from Roanoke the next morning. I installed it and had the exact same experience: no throttle response, check engine light, Failsafe mode. I returned the second TPS for a refund. I then called a Ford dealer. I purchased a Motorcraft TPS. It had proper indexing for the throttle shaft. I pressed it into position, installed the new factory screws at 27 inch pounds, then reconnected the electrical connector for the TPS and the negative battery cable. I had the car up and running with perfect throttle response and no check engine light within about 20 minutes. By contrast, I wasted over 3 hours on 2 EC3337 that were bad from the factory. My Advance store has excellent service quality. Too bad the manufacturing quality of the BWD EC3337 was so poor. Unfortunately, I cannot recommend this part.

Comments about BWD Throttle Position Sensor:

Purchased one for a 2005 F150 5.4l. Installation was straigt forward. So here it is: First one I purchased was already used..it I did not work at all. Had to drive to a whole other store to get a replacement: I stalled it, and it still did not work. Removed and installed the old one, truck started up fine.
Yes - I reset the PCM
Yes - I had no codes thrown till after new ones were installed.
I think the electronics are not compatible OR they are sent with such a loose potentiometer, it rotates to fully closed position. However now way of knowing.

          low idle speed and hesitation problem solved!

              Comments about BWD Throttle Position Sensor:

              2004 Explorer XLT with V6 K-flex fuel, 99k miles, K&N air filter and Pennzoil 5W-30 full synthetic oil plus high efficiency oil filter every oil change. This was the first engine issue since owning in 2007, OBD2 scanner brought up P0193 and P0463 codes. This purchase was to solve the P0193 code first, based on Explorer forums and the AAP reviews on this throttle position sensor (TPS).

              Was having momentary low idle on startup (500-700 rpm) and significant hesitation at ANY speed, especially highway up to 65-70 mph... pushing the accelerator pedal would typically have zero response until backing off then slowly pushing down again.

              Check this item before you leave the store. TPS is solid and made of 30% glass-filled PBT (typical of automotive connectors), good construction, comes with two torx screws with same blue thread locker applied as original screws from the factory, including washers in a sealed plastic bag in the box.

              Ran the vehicle at least 10-15 minutes to warm up under the hood for the sake of the factory TPS screws to loosen up without breaking. Then removed the intake tube between the air filter box and throttle body. Then sprayed and cleaned the throttle body with Valvoline heavy-duty carb and throttle body cleaner. There was a small amount of dirt and black greasy carbon to wipe out but it seemed to resolve slight mechanical binding where the butterfly valve shaft meets the throttle body housing at both sides. Then I removed the electrical connector off the old TPS, carefully loosened and removed both old torx screws which takes some time and the old TPS slides right off the butterfly valve shaft end.

              Make sure the new TPS inner metal tabs (inside shaft hole) are rotated to the proper position to work with the butterfly valve full travel rotation, and the two metal tabs slide along the longer sides of the rectangular butterfly shaft end. Push TPS towards and against the throttle body and rotate it until the TPS housing plastic tab is fully seated into the throttle body hole, sitting completely flush against the throttle body. Carefully replace both screws to correct tightness and re-connect the electrical connector and its plastic slide lock, then put the intake tube back into place. Don't forget to re-attach the PCV tube into the intake tube.

              On the first start, the engine fired right up to almost 2000 rpm then slowly dropped to idle speed around 800-1000 rpm like it's supposed to. Every single time stomping on the accelerator provided INSTANT response and full power the way it's supposed to. Hesitation problem solved! So glad I decided to buy it along with the carb and throttle body cleaner!

              ordered online to pick up at my local store upon recieving i noticed the box was greasy ask why and the employee says one of them could have had dirty hands and opened it. so i put on and the results where the same so i ordered another. this one came in a sealed bag inside the box which the other did not. i put this one on and it worked. then i took the broke one back to get a refund. bottom line is you get what you pay for but i would recommend this to get you by.

                                Hi Kenney, happy to help you! Symptoms of a Faulty Throttle Position Sensor: An unexplainable bucking and jerking in the vehicle. Sudden idle surges. Sudden engine stalling without any apparent reason. Hesitation while accelerating. Sudden surges in speed while driving on the highway. Intermittently flashing of check engine light for no apparent reason. Difficulties in changing gears. A drastic drop in fuel economy. How to Test a Throttle Position Sensor: You can use a standard ohm meter to test a switch and combination type throttle position sensor and a volt meter to test a throttle position sensor that uses a potentiometer. Check the resistance in various accelerator pedal positions, record the resistance and compare against values listed as acceptable in a quality car repair manuals such as Chilton or Haynes to determine whether or not the sensor needs to be replaced. Haynes Ford F-Series/Expedition Repair Manual (Part No. 36059).

                                The function of the throttle position sensor is to supply information to the car's computer about the position of the car's throttle. Malfunctioning of throttle position sensor can result in improper data being fed to the car's computer, which monitors engine performance, in respect to the fuel efficiency of the car. Symptoms of malfunctioning throttle position sensor are: 1). Bucking and jerking of the car. 2). Idle surging of the car. 3). Sudden stalling of the car engine. 4). Hesitation while the driver of the car is trying to accelerate. 5). Sudden surge in car's speed while driving on the highway.

                                Usually you will have to adjust it so that the idle on your vehicle is right.

                                This sensor should be located attached to the throttle body. Where the tubing from the air filter connects to the opposite end.

                                Yes the TPS could be the cause of the loss of throttle while driving. The TPS is a potentiometer, which means it has a contact arm that moves over resistors.If the resistors or contact arm is worn then it could cause loss of throttle while driving.

                                On the throttle body, at the top of the intake, usually opposite side of where the throttle linkage connects on the throttle body. Look for a wire harness connector and wires on the throttle body.
