I scanned my 06 chrysler 300 abs.it said left front wheel speed sensor.i changed it.now it says the right front wheel speed sensor.when i scanned it.abs light stays on brake light stays on and blinks when put in gear.esp bas light also on and stays on.can not turn esp off at button.need help please.

Brent, Check and clean connections(use electronic contact cleaner), make sure wires are not damaged. Check grounds from EBCM controller. Check links below and don't be afraid to google search for more info.

How fixed Chevy with an Abs and Brake light on

How To Install Replace Front ABS Sensor and Harness 2000 06 Chevy Suburban...

Hi
The wheel bearing may carry the magnetic ring that the abs sensor uses to pick up a reading.
Replace bearing if its faulty and retest all as before.

Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

here is the link for the part you need.

Simple as pie. Once you have the part in hand, You will see where it plugs in near the intake. Just follow it to the other end, remove and replace.


Should be a 10mm bolt holding it down, and to remove the plug, just press the retainer tab and pull out. New plug snaps right in.

HAVE VECHICLE CODE SCAN.SOUND LIKE YOU COULD HAVE BAD WHEEL SENSOR OR DISCONNECTED OR LOOSE WIRE.BECAUSE 4WD DRIVE NEEDS SIGNALS FROM WHEEL SPEED SENSORS AND VECHICLE SPEED SENSOR BEFORE AUTOMATIC TRANSMISSION AND TRANSFER CASE CAN SHIFT CORRECTLY.

sounds like wheel speed sensor or air gap on sensor causing intermittent loss of signal, wheel bearings that have play can cause similar condition. With a scanner you can check to see what history codes may be present, if the light(s) are not on when you scan it or have it scanned. Hope this helps

sounds like your abs trac control module is going its located on the front drivers side behind wheel well cover , 850 for new best to pick up from junk yard about 100. module changed in 2002 . make sure you get right year .mine went lost all break fluid no warning canister rusted out.

you need to check for voltage to sensor from module or a broken wire,also with a multi meter check for resistance from sensor from turning wheel

I do not beleive that there is a specific test for the speed sensors that measure the resistance of the sensor, if there is you should be able to measure the opposite wheels and figure out what it should be.

The best way to figure out what sensor is bad is to have it scanned, it may not be a sensor at all.

There are several TBS's and recalls on the wheel speed sensors, call a dealership and find out if yours qualifys.
