Question about 2006 Pontiac Grand Prix

Open Question

My abs system is all messed up i have 3 current codes for it and i am wondering how to go about fixing it? the first code is a C0245 wheel speed sensor frequency/ ebcm control valve circuit. The second code is a C0041 rf wheel speed circuit range performance. And the third is a C0035 lf wheel speed sensor circuit malfunction. This is exactly how the scan tool read it and im wondering if just replaceing the wheel speed sensors will fix it?

first thing to do, go with the replacement of the light bulbs, high beam and low beam are two different fillaments on the ligh bulb, as for the rear also replace the bulbs, when your flasher rellay flashes faster, it means that there is less drop of current in the circuit, like only one light bulb working.

The trouble codes are for the left front and right front wheel speed sensors. You should open your hood and in front of the engine on the drivers side under the air filter box you will see a silver tube shape object which is the air condition dryer. Look for your main wiring harness that pass near it. The harness can rub on the dryer and cause many different electrical problems including abs problems. If you see the harness rubbing on the dryer you can move the main wiring harness with your hand to see if there are any cut wires. If they are then you will need to repair the wires that are damage and reposition the harness to it will not rub anymore. This is a common problem with the pontiac grand prix.

Good Luck!!

Speed sensors commonly go bad and need to be replaced. If you replace the bad sensor it should solve your problem. I hope this helps and if you have any other questions please feel free to ask.

Refer to Variable Effort Steering System Description and Operation in Variable Effort Steering

Your best bet , take it to the dealer .
Variable Effort Steering System Description and Operation
The Variable Effort Steering (VES) System varies the amount of effort to steer the vehicle as wheel speed changes or lateral acceleration occurs. The Electronic Brake Control Module (EBCM) controls an actuator located in the steering rack and pinion. The actuator consists of an electromagnetic coil and a pintle valve which moves in and out of the rack and pinion's input fluid orifice, regulating power steering fluid flow. The EBCM commands current from 0-1 amp to the VES actuator which varies the amount of effort to steer the vehicle. At low speeds, 1 amp of current is commanded to the VES actuator and the pintle valve is fully retracted which provides maximum fluid flow and maximum steering assist for easy turning and parking maneuvers. At high speeds, no current is commanded and the pintle valve moves closer to the orifice, decreasing fluid flow, providing firmer steering (road feel) and directional stability. The VES system uses the steering wheel position sensor input to calculate lateral acceleration during abrupt driving maneuvers. The system also uses the Antilock Brake System (ABS) wheel speed sensor inputs to determine vehicle speed. The EBCM is constantly monitoring these inputs to achieve the desired current to the VES actuator. The EBCM has the ability to detect malfunctions in the VES actuator or the circuits to the actuator. Any malfunctions detected will cause the VES outputs to be disabled and the EBCM will command the Driver Information Center (DIC) to display the SERVICE STEERING SYSTEM warning message via a class 2 serial data circuit.

Abslight stays on. How to fix? This is a2007trailblazer?

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Brakes abs light and pulsating brakes

Too many possibilities. You need to have a scanner that does abs systems used on it and see what the codes are. This could be anything from a faulty wheel speed sensor to a bad abs module.

I have a 02 grand prix the abs light and trac off light came on and when i push my brakes half way down it makes a grinding noise got codes c0040 and c0245 from auto zone what is the problem please help i...

c0040 indicates right front wheel sensor, so problem is more than likely sensor or wiring to it. c0245 indicates wheel speed sensor frequency error. This confirms wheel sensor or wiring.

I have codes C0040 and C0245 which relate to the

it is likely the sensor but I would test it before you replace it. you will need to check the resistance on the wires coming off the sensor you will also need to know what the right resistance is.

Does abs shutt off four wheel drive

I suggest scanned the ABS module in order to know fault codes stored there; sometimes just need speed wheel sensor adjustemtn, but need the real fault code in there.

The abs light on my 2000 buick lesabre will noy shut off we have changed brake rotors and pads what could the promblem be

The ABS system has nothing to do with replacing the pads and rotors, the abs is anti braking system the system is designed to keep the wheels from locking up when brakes are applied hard, . you will first need to have the abs computer scanned for codes, the computer will pick up a problem in the system and turn off the system and then turn the abs light on and last it stores a code in the computer, the code will tell you what part of the system has failed. the codes or code are very helpful in pinpointing the problem. the abs system contains speed sensors on all four wheel and a anti braking module and computer, the most common reason for a abs code is a bad wheel speed sensor. this is the most common problem seen, the code for example may read something like this poXXXXX right front speed sensors.again start by getting the codes,good day.

wheel speed sensors and a few other things can cause this.Check you fluid level and fuses, usually it is a speed sensor but without scanning the system for a code it is hard to say.

Sounds like a steering wheel sensor. Call Mitsubishi back and tell them that, or try a different dealer. Sensor detects the angle of the steering wheel when determining ABS operation parameters (I think)...
