ABS, ESB Handbrake lights on

[a_ibrahem]

Hello Guys,

I have 2007 liberty sport with 220K on clock

recently i got ABS, ESB, Handbrake and slide marks lights on in the dashboard

i have read a lot and found a common issue about rear sensors wires,

i did ohm test straight from ABS module connector after disconnecting the senors and wires are ok, the i connected the sensors and measured again and all sensors giving a reading around 380K Ohm, except for rear right is giving 5.5M ohm

have anyone found such symptoms before ?

or know how to test sensors or what value it should be in ohm test ?

Thanks lot guys,
Ahmed

I have the same problem but that's because the rear diff sensor has completely severed from the wires to sensor. Corrugated roads are a b##@*! Ive ordered a new sensor and will have to try and wire it up when it arrives.

Not knowing the exact ohm spec but 380k ohm is is way over any spec I've ever ran into for a ABS sensor.Heck 5.5m ohm is way to much.

Most that I test and are known good have 50 ohm's or less.

After removing old rear right sensor found lot of metal dirt stuck on it, cleaned it and and measured it and it shows around 380k again

Connected it back and no alarms since then

Thought I update u guys

Thanks,
Ahmed
