P07BF - 00 - Input - Turbine Shaft Speed Sensor 1 Circuit Low For a complete TRANSMISSION wiring diagram, (refer to the Wiring Information) . Theory of Operation The purpose of the diagnostic is to check the turbine speed sensor circuit for electrical failures by continuously monitoring the sensor output circuit for voltage high, low, or open conditions. The turbine speed sensor is a Hall Effect sensor that has an output range that alternates between normal high and normal low voltages as the turbine tone wheel rotates. If the measured turbine speed sensor output circuit voltage is greater than or equal to a calibrated high threshold (circuit high) or is less than or equal to a calibrated low threshold (circuit low or open) for a calibrated amount of time, a DTC will set. When Monitored and Set Conditions When Monitored: This diagnostic runs continuously when the following conditions are met: • TCM supply voltage is between 10 and 16 volts. • Engine speed (CAN message) is greater than 550 rpm. Set Conditions: • Input speed sensor output circuit voltage is less than or equal to 0.225 volts for less than 1 second.

AirDog Draw Straw installation You will need a 15mm socket and 1/2 ratchet for the bands on the tank. You'll also need a flat blade screwdriver, hammer, floor jack, and a ratchet strap. The way I remove the fuel tank is to place the jack under the tank just to support the weight. Then wrap a ratchet strap around the fuel tank and hook it to the jack pivot pin. Tighten the strap lightly not enough to crush the tank. You need to take a screwdriver and hammer and lightly tap on the sender ring and loosen the ring up to allow the sender to stand up out of the fuel tank. No need to unhook any lines leave that alone for now. Now using a 15mm socket you can remove the two nuts holding the fuel tank bands up to the frame. Pull your bands down and might have to bend them a bit to get out. Then easy the fuel tank down to the floor slowly and carefully to the floor watching the sender not to damage the fuel, sender in the tank, Once the tank is on the floor the sender can be lifted out of the fuel tank and the fuel tank moved out of your way. NOTE: You'll want to have a friend or buddy help you tip the tank over and dump the fuel out of the tank. The tank needs to be empty as much as possible to get the measurement correct. The current AirDog Draw Straw is different than the older generation I have in my truck. Make sure to support the tank at the normal band locations with 2x4 boards. WARNING: Do not leave the tank laying on the floor for measuring or any work it will deflect the tank bottom inward and skew your measurements also will create the 1/4 tank slosh issues! This now requires a 1-inch hole drilled into the top of the tank. You will need to inspect the location of where you're going to install that draw straw and be sure there is nothing going to interfere with the lines or the bulkhead sticking up. Make sure to clean the area where you are going to drill the 1-inch hole. Now drill the hole and collect all the drilled crumbs without getting into the tank if possible, Grab two quarters and lay them in the bottom, and stack the straw on top of the quarters. Now using a Sharpie mark the straw at the top of the tank. Now you want to measure from the bulkhead down to your mark and take note of that measurement, Now measure from the tip back up to the same measurement and mark the cut line. NOTE: If you are using 1 quarter you want to follow the AirDog method of holes drilled in the straw. If you use 2 quarters then no notches should be required. WARNING: Cut the straw "straight". Do NOT cut the straw at an angle or anything else but straight. When the straw is cut now place the sealing washer on the bulkhead and install the draw straw. The flat washer, star washer, and nut go inside to nut the straw in. You'll want to check the gap in the straw tip to the tank bottom should be the same as the number of coins you used for the gap. The closer the better for the tip. No, the tip will not suck to the bottom, the weight of the fuel will deflect the bottom downward making more of a gap when filled. This is why closer is better. Now just install your fitting into the bulkhead connector. Now you can reinstall the fuel tank which is super easy being the fuel tank is empty and light to lift up by a single person. Just reverse the process.
