CODES: B0050, that's the rear wheel speed sensor B0455, steering wheel angle sensor---- where can i purchase and prices for that part please? P0300, random multiple misfire detector---tune up right? P0351, ignition coil A primary/secondary circuit-------what does this operate and price for part?
Your best bet ,take it to a qualified repair shop ! P0351, ignition coil A primary/secondary circuit-------what does this operate
The electrical circuit for the coil for cylinder # 1 , could be the wiring , coil or the driver (transistor)inside the PCM - engine computer . Replacing the PCM would need to be programmed , DEALER ONLY . Just replacing parts isn't going to fix this . Doing the diagnostic's for the code . Codes don't tell you a part is bad or needs to be replaced . All codes have a diagnostic test procedure that has to be followed to find the cause of the code setting . Don't know where you came up with B0050 & B0455 Has nothing to do with traction control . These codes would start with C . tune up right? No .
trk won't go ???????
C0445 This has to do with the rear wheel steering system !
The steering wheel position sensor (SWPS) provides one analog signal and 3 digital signals. The digital signals, Phase A, Phase B and marker pulse, are direct inputs to the rear wheel steering control module. The analog signal is input to the BCM and is sent via a class 2 message to the rear wheel steering control module. Battery voltage is supplied to the sensor from the cruise fuse to operate the digital portion of the sensor.
A 12-volt reference is provided by the rear wheel steering control module to the Phase A, Phase B, and marker pulse circuits of the SWPS. The module monitors each circuit as it is either remains high or is pulled low by the SWPS.
The scan tool displays the Phase A and Phase B data parameters as either HIGH or LOW when the steering wheel is being rotated. Each change from HIGH to LOW, or LOW to HIGH, represents one degree of steering wheel rotation. When observing the Phase A and Phase B data with the scan tool, the parameters will not always display the same value at the same time.
The marker pulse is a digital pulse signal that is displayed as HIGH by the scan tool with the steering wheel angle between +10 degrees and -10 degrees. At greater than 10 degrees steering wheel angle in either direction, the marker pulse data will be displayed as LOW.
The BCM provides the 5-volt reference and low reference for the analog portion of the SWPS. The BCM reads the SWPS analog signal in voltage, which is typically 2.5-volt with the steering wheel on center. The voltage ranges from 0.25-volt at approximately 1 full turn left to 4.75-volt at approximately 1 full turn right. The voltage will then remain at that level for the remainder of steering wheel travel. This voltage can be monitored in BCM data display.
The rear wheel steering control module receives the analog signal via a class 2 message from the BCM. When monitoring the rear wheel steering data, this information is displayed in the Steering Wheel Angle (TBC) Data parameter, and is shown in degrees. The range of the display is +/- 225 degrees, with negative numbers representing steering input to the left, and positive numbers representing input to the right.
This does not mean the sensor is bad !!!!!!!!!! Take it to a qualified repair shop before you make it non fixable .
Quadrasteer™ is a 4-wheel steering system that dramatically enhances low speed maneuverability, high speed stability, and towing capability. The system is an electrically powered rear wheel steering system comprised of the following components:
You have no idea what your messing with .
Rear Wheel Steering Control Module: The rear wheel steering control module controls all functions of the rear wheel steering system . The module has a dedicated power feed line from the under hood fuse holder. The fuse is a 125 amp mega fuse . The wiring is routed to the rear of the vehicle. The rear wheel steering control module is located above the rear mounted spare tire. The rear wheel steering control module uses the inputs listed above to determine when and how far to turn the rear wheels. The rear wheel steering control module also uses the hall switches in the steering gear motor , shorting relay , and motor control relay to monitor and control the direction and speed the motor operates. The rear wheel control module also controls the duty cycle of the phase leads to the motor . The motor control relay is part of the rear wheel steering control module and is not serviceable . The rear wheel steering control module uses both a class 2 and a discrete vehicle speed sensor signal . The system will not function without a discrete vehicle speed sensor signal . The rear wheel steering control module uses the 2 vehicle speed sensor signals for comparison purposes . The TBC sends a class 2 message for the analog portion of the signals from the steering wheel position sensor. The rear wheel steering control module uses inputs from the steering wheel position sensor to determine steering wheel position and rate of change. The rear wheel position sensor signals provide the rear wheel steering control module with rear wheel position data. The rear wheel steering control module will send out a class 2 message to the IPC to turn on and off the amber Service 4-Wheel Steering System Indicator. The rear wheel steering control module controls the indicators in the mode switch on the dash .

mar82is, Mario, Yes a PO300 code is for random misfires. This is an issue with the spark plugs, wires, and coils. What you should do is to pull all the wires, one at a time, and inspect the terminals that connect to the spark plugs and the coil. If they are corroded then replacing these will help to alleviate the problem. Also check the spark plugs. See if they are wet and smell like gas. If so then this will be one of the misfiring plugs. A properly firing spark plug will have a gray color to them. If they are black and sooty then you should replace them. To check the coils, what you can do is purchase an in-line spark tester. You will find these at any auto parts store and they are not expensive. Place the tester on the spark plug and reconnect the wire to the tester and watch the light as it flashes. Should you see any gaps in the time that the coil fires then you have a bad coil and this will need to be replaced. DO NOT try to connect this tester with the engine running. It is rare, but the fuel pump will cause this condition as well. This will be from a weak pump or a clogged fuel filter. What to do here is, If you have one, connect a fuel pressure tester to the schrader valve on the fuel rail and watch for any discrepancies in the pressure as the engine runs. If there is, then I would start with the filter because the pump is in the tank and this will have to removed from the vehicle to replace it. Good luck with this.

Those 2 codes together usually mean there is a vaccum leak(the intake is getting air that is not metered through the mass airflow sensor).Look for PCV and vaccum lines loose(you might have got it by repositioning the air cleaner)
