Question about 2006 Chrysler Pacifica

1 Answer

ABS Light came on and goes off. I have checked all of the ABS wheel sensors and they all OHM out at 558. Based on what I have read, if they are close to the same they are good. Trying to figure out what to check next.

If the fluid level is good and the sensors are good your problem is either the Master Cylinder or the ABS control module. If you have no problems braking it is the Control module. If you've noticed a braking issue the problem is the Master Cylinder.

Can you show pictures of a ABS wheel sensor?


THE ABS WHEEL SPEED SENSORS ARE PART OF THE WHEEL BEARING ASSEMBLIES.THEY ARE A 2 WIRE HALL EFFECT SENSOR. DISCONNECT THEY HARNESS AND USE A DVOM (DIGITAL VOLT OHM METER) SET ON AC VOLTAGE AND SPIN THE WHEEL WHILE CONNECTED TO THE SENSOR IN THE WHEEL BEARING. IF YOU DONT GET A READING REPLACE WHEEL BEARING. IF YOU DO ITS A WIRING ISSUE BETWEEN SENSOR AND ABS MODULE.

How do i get the abs/ yellow triangle of I've


I quote some details from BMW's owners...
Symptoms: Dreaded yellow triangle, ABS light, and CEL on. All other functions (speedo, tach, cruise control, trip computer, etc) working.

Procedure: Pull the ABS controller out and disconnect it from the wiring harness. Mine is under a panel to the left of the glove compartment. Remove the wiring backshell so you can get at the wiring connections on the back side of the connecting plug (you need to be able to see the colors of the wires and get a Ohm meter probe on them).

Using a Bentleys Electrical Manual find the connection diagram for the wheel sensors to the ABS Controller. The pin designators will most likely be wrong (they were for mine) BUT the color designators for each of the wires is correct.

Example: Right Rear sensor is connected by two wires, one blue and one blue green.

Connect Ohm meter across these two pins. NOTE: I wound paper clips around the probes to make a very small probe tip which helps. Write down the resistance reading. Mine was 3.08k ohms.

Work through the other 3 wheels and write down the resistance readings. If any of the pairs is open (i.e. infinite resistance) you have a bad connection between the ABS Controller and the wheel sensor. You can then remove the affected wheel, unplug the sensor, short out the pins on the plug (not the wheel sensor part but the chassis wiring part) and if the ohm meter is still reading open you have a broken cable between the wheel sensor and the ABS controller. If the cable is good connect the ohm meter across the wheel sensor itself and if the cable still reads open you have a bad wheel sensor, replace and retest.

Here is what I found. All wheels read 3.08k ohms except the right rear which read 4.4M ohms. This sensor was replaced during my rebuild exercise and it looks like they provided the wrong part. I replaced the part with a dealer item and retested. 3.08k ohms was read with the new part. Reconnected everything and the ABS light went out, the yellow triangle light went out. I used my OBDII computer interface to clear the CEL light and all is well again.

Total testing/repair time: 2hrs and 35 minutes!

Here is my theory. The "older" ABS Controllers (like mine) use sensors with the lower reisitance (3.08k ohm) while the newer Controllers use the higher resistance sensors (4.4M ohm). The part I bought was from a 02 E39! I can return it but I think I will use it to test my 00 528 problems first.

Additionally, I suggest check charging system (alternator/power module/battery) has a defect that a professional BMW technician should look at, Most probably the alternator is toast.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Toyota cavalier 1996 the abs light, how?


Toyota cavalier??? Chevy tacoma???
You might have a wheel sensor issue (part of the wheel bearing assembly) It tell the abs computer the wheel speed, and if one is bad, it will error the abs, and turn the light on. You can get this checked with an abs scanner hooked up, or ohm out all of your speed sensors with a meter.

300zx 1990 brakes work done rotor pads, fuel check and abs light still on sensor was replaces , what else I can do to get that abs light off ?


A component of your abs system is likely bad. It may be and usually is an abs wheel sensor that goes bad. Have the abs trouble codes read to find out exactly what is bad.

Brake and abs lights are on intermittentedly


you need to see what the abs code is for as it will turn on the red brake light.you need to know what this is to repair.check the brake fluid level in the master cylinder just in case thats all it is.

The ABS light is on my 2006 Chrsyler Pacifica Touring


Each wheel has a sensor. Theres more to it than the sensors. have the repair shop check it over for you and recommend repairs.

1998 f150 abs and park light on fluid good, feel no dragging


ABS light being on could be a bad sensor or broken wire to the sensors. ABS is on the front brakes, check the front wheels inside for wiring going up to the main ABS ecu mounted at the master cylinder. Check the wires from at the bearing assy. then follow up to the ABS ECU or the brain, for any cuts or nicks. You can have a bad wheel sensor you check these with a volt/ohm meter, Find the plug at the wheel and unplug it ck for ohms should read like .018 ohms. If you raise the wheel and spin it you can then read volts, depends on how fast you spin the wheel you can get 2-3 volts. .

2002 gmc abs light is on tested sensors with ohm meter right hand side tested 15 ohms and left side tested 0 ohms where is my problem.


all sensors will read different depending on the wheel. so hookup ohm test again and then spin the wheels the ohm range should vary from 0 to 50 ohms both side should match. the side that remains constant or at 0 is faulty.

ABS brakes shudder


YOU NEED A SCANNER TO MONITOR THE WHEEL SPEED SENSORS. THE ABS IS SENSING A SKID AND THE ABS IS ACTIVATED WHEN THIS HAPPENS. THERE MAY BE A CODE FOR THE HUB THAT IS CAUSING THE ABS TO ACTIVATE.

CHECK THE WIRES FROM THE SENSORS FOR BREAKS OR CHAFFING. AN OHM READING OF THE SENSOR SHOULD BE 850-1200 OHMS, AND AND A-C VOLTAGE READING SHOULD BE 100 MV WITH YOU TURNING THE WHEEL BY HAND.

Ford Windstar ABS icon remains on. Is this something I can repair myself? If yes, how do I go about it?  I've been told it will cost several hundred dollars to replace a sensor.


It is fairly simple to check a wheel sensor to see if it is indeed faulty. You need to be able to have access to each plug connector on every wheel sensor and an OHM meter. To test, unplug each sensor ( 1 at a time and you do not need to have the ignition on). Set the multi meter to read OHM's, put one the probe wires on each pin ( wheel sensors normally have only 2 wires) and if the wheel sensor is OK you will show some resistance readings in OHM's. If your meter shows NO reading then that is the sensor that will need replacing. To be really sure check each one and write down the readings. Don't forget to only check the wiring from the wheel sensor to the plug connector. If it is a sensor they are fairly simple to change but you will need to jack up the van and remove the road wheel to gain access. Once repaired the ABS light should go out but will stay in the ECU's memory (that can be erased at a later date using a scanner/code reader). Hope this helps.
