On grand prix2006 code C0040 which weel is that my computer tell me rear but no side


It is the right front (RF) ABS sensor that this codes corresponds to nothing to do with the rear.. Are you using a GM TECH 2 scanner? If not that is the problem.

1774 and 1775


There is probably no need to contact the BAR though you always have the right reserved. Trouble Code P1774 indicates your Mini's rear wheel speed sensor lost its signal, and trouble code P1775 indicates the right rear wheel speed sensor lost its signal as well. Both more than likely triggered during the dynamometer portion of the smog check inspection; while the front wheels are turning and the rear wheels are stationary. During this time, as far as the ABS system knows, the rear wheel sensors have lost their signals.
After a computer reset and driving your Mini Cooper for a few miles everything should return to normal, as apparently they have; and you've passed the smog check. Should the check engine light return in the near future for the same trouble codes P1774 and P1775 we'd recommend inspecting the rear wheel speed sensors for possible debris build-up. Since these trouble codes where triggered during the smog check and smog check machine failure we can assume the trouble codes were temporary and not related to any physical problem with your Mini Cooper.

Action tractive, abs--trk won't go


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 .

Quadrasteerâ„¢ 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 .

Subaru 97 speed sensor trouble code p0500 not passing admissions.. what part to I buy and where is the sensor located?


There are actually two Vehicle Speed Sensors (VSS). I'm going to assume you have a 2.5 liter engine and an automatic transmission.

The Vehicle Speed Sensor 1 (output shaft rotation sensor) is mounted to the extension case (from the outside of the case). The sensor outputs a pulse signal which is transmitted to the TCM where it is converted to vehicle speed.


The transfer clutch drum is connected directly to the rear wheel driving propeller shaft. Vehicle speed sensor 1 on the AWD model detects rear-wheel speed.

Vehicle Speed Sensor 2 provides vehicle road speed information to the ECM. The ECM uses this data to properly determine ignition and fuel delivery curves. The sensor consists of a reed switch and magnetic rotor turned by the speedometer cable.


One rotation of the magnetic rotor opens and closes the reed switch four times, producing a digital signal which is converted to vehicle speed by the ECM. The sensor operates whenever the vehicle is moving with ignition ON. As the transmission rotates, the speed sensor sends a pulsed on/off signal to the ECM.

The speedometer uses VSS 2 for it's signal.

Hope this helps (remember to rate this answer).

2005 nissan almera,1.5letre.. fault code po725


P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Keep us updated.

Abs light and brake light are on. also service


You can test the wheel speed sensors by unhooking the connectors and put ohmeter test leads on the sensor terminals should read around 1100-1600 ohms also the connectors themselves were bad for wires breaking inside the insulation at the connectors from flexing when the wheel is turned back and forth..Note excessive wheel bearing noise from bad bearings have also been known for interferring with clean abs signal also causing abs codes good luck

Have error codes C1175 & P1000 for a 2002 Jaguar X-type 2.5.


C1175 ABS/TCCM Anti-lock braking / traction control LH rear wheel speed sensor circuit fault ABS/TCCM to wheel speed sensor signal circuit (FH33-21): open circuit, short circuit to ground, short circuit to B+ voltage, high resistance LH rear wheel speed sensor failure
P1000 is for check not complete after last memory clear , dont worry about it , just stick with C1175 , and most probably it is the sensor wire
