P1211. ABS, ESP and slip light

Engström · Feb 20, 2019

Hello! During this weekend I’ve got some new troubles with my Navara. The abs, esp and slip light came on for a while. And then after I stopped at the fuel station it went of and the systems worked again for 1km. Then the slip light came on and cut down the engine power and after some more km al the lights came on again. And I couldn’t put it in 4wd. And then when I was parked the speedo jumped. I did the pedal thing and got the code 1211. After a hard reset and a little drive there aren’t any codes but the lights still on.
Anyone had this problems?
Abs sensor or the abs unit?

It is very likely to be a sensor. It is the rear left hand sensor which sends the road speed to the speedometer, it is either faulty or not connected properly.
If you have a multimeter you can check the resistance of each sensor. They are not expensive to replace.

Yes i really hope it’s a sensor.
Now I’ve checked the sensors with the multimeter set on ohm 20k.
LF 15,67
RF 15,56
LR 16,02
RR 15,44
Is this difference enough to assume the LR sensor is faulty?

No. That just means the pickup coils in the sensors are not open or shorted.
A sensor could still be faulty.

The most common thing is that one of the sensors is showing an open or closed circuit.
It is still possible that there is a plug issue or that sensor is misaligned, the rear being the most likely.

Thanks for your help.
Is it only the left rear that can make the speedo jump?

landmannnn · Feb 20, 2019

I believe so.

Engström · Feb 20, 2019

Ok thanks. I’ll try to find a new one tomorrow!

Problem solved. It was the right rear abs sensor.
