error code of P1824

Question: I took my 2002 Ford Explorer to the repair facility with an error code of P1824. After extensive research on their part, or so they say, they stated that the electronic shift control module needed replacing so the 4x4 high light would stop blinking on the console. We have replaced this part and the light is still flashing, after unplugging battery for five minutes to reset the computer. They cannot figure out what is wrong. Any suggestions??? Answer: Replacement of the 4WD control module does not require programming using the Ford scan tool on this vehicle. Vehicles built after 03/04/2002 with the 11th digit of the VIN being (U) or vehicles built after 03/11/2002 with the 11th digit of the VIN being (Z) require a different module than those built before these dates. The modules are not interchangeable though the harness connectors will plug into either of the modules. The modules have different internal designs. The 4WD shift module is located forward of the glove box, under the passenger side of the dash. 1. Check the resistance of the magnetic clutch coil at the transfer case measuring between terminal 16 and terminal 11 of the shift motor connection. Terminal 16 connects to a Brown (BN) wire on the harness and terminal 11 connects to a Brown/Yellow (BN/YE) wire on the harness. Resistance should indicate a reading of 2.5-3.0 ohms. 2. Use a scanner to try and command the 4WD clutch on. If this is possible, monitor the voltage on the BN wire while increasing the command on the clutch. If there is low or no voltage to the clutch no matter what the command, check the powers and grounds to the module. 3. The Four Wheel Drive (4WD) module is located behind the glove box area. A. C281a pin 1 Black/White (BK/WH) and pin 2 White (WH) should be battery voltage at all times. B. Pin 9 Violet/Orange (VT/OG) should be battery voltage with the key on. C. Pin 10 Orange (OG) should be battery voltage with the key in the crank position only. D. C281b pin 16 Grey/Yellow (GY/YE) should be battery voltage with the key in the run position. 3. The grounds are C281a pin 7 Black (BK) and C281b pin 2 Black/Light Blue (BK/LB). 4. If the powers and grounds are OK, replace the 4WD module. Be sure to get the correct module, the early and late build modules will plug in but are not interchangeable.

Question: I have a street rod with a General Motors 350 engine, just replaced the (Accel) coil, coil cap, mag pick-up and control module. I have reset the air spacing. and now it won't idle. I think I should now recheck the timing but don't no what that would be. The engine is stock except for the cam and i have no idea what the duration etc. would be. where do I start. Answer: Start at 4 degrees BTDC. this is stock, then add 2 degrees(advanced) and test drive, keep adding 2 degrees until you hear it ping and back it off 2 degrees. this is the optimal timing for performance. back it off 4 to 6 degrees from engine ping for more drivable/easy to start conditions. If you have Nitrous Oxide, then remove 2 degrees for every 50 hp of Nitrous.

Not a huge savings but its enough to buy lunch. I guess the engineers that designed the fuel pump/sending unit as a complete module figure if your going to bother dropping the tank you might as well replace both, so they made it convenient for you without considering the price...lol. If you search : "Fuel Pump FG0289" You'll find several listings. A list of online auto parts stores to check out here. Found it for $182.46@ http://www.nextdayautoparts.com/

knocking noise

Question: 2002 V6 Camry..had both strut mounts (rubber) replaced today but it did not fix the knocking noise when the car slowly goes over a speed bump. Sound like something is knocking on the frame...can feel it through the steering wheel. any suggestions? Answer: Strut mounts are the most common source of front end noise on late model Camry's. Were the strut mounts installed by a Toyota dealer or someone who is knowledgeable in Toyota and were the parts genuine Toyota mounts? 2 other things that need to be checked, not common but most likely if it is a low speed knock- 1-the sway bar links that connect the sway bar to the struts need to be checked for free play, these must be removed to replace the strut mounts and may be loose from improper installation or may have joint free play causing them to "pop" when the front end flexes over a bump and twists the sway bar. I would also recommend checking the rubber bushings for the sway-bar, they are located in the center of the sub-frame rear area and insulate and retain the sway bar to the frame. I checked the Toyota technical database and the only Service bulletin related to your type of noise is for the steering intermediate shaft, this will cause a pop noise when the steering wheel is moved back and forth at low speeds.
