Abs sensor ohms

[Sudesh]

My main computer is down, so don't have access to my service manual right now.

So was hoping someone could help me out, was looking for the resistance it should read on rear sensors?

I'm thinking its 840 or there abouts? I have an NSX in that was throwing up the code for one of the rear sensor, so just want to double check the resistance on it before going further.

Hi, Sudesh.
Tried to send this info through SMS while the site was in the upgrade process.

It depends on the temperature but when I measured it at about 5 – 10degC, it was showing at about 847 – 850ohm so your initial comment is correct.

Please note that even if the sensor is showing the above ohm, if you have the upgraded ABS, it can still trigger the ABS error code #12, 14, 16, 18 that are for the signal quality issue and almost all of the cases were caused by the intermittent failure of the wheel speed sensor despite the good ohm reading.

The classic ABS won’t be able to detect it so no ABS warning light but instead, it will kick back the brake pedal even none of the wheels were locked up.

Hi Kaz,

Got your text and tried to reply. I just got a new android phone and trying to get used to all this fancy touch screen thing, apps and various setups lol I'm used to old type phones with buttons lol

The car I received in last week is a UK 1992 model, it still has the old type 1 ALB system, rear sensors are showing 830 without side temp at around 5 degrees yesterday.

The owner said the lights clear at initial start up, but after 5 mins driving ALB comes on, closely followed by TCS and then sudden loss of power, power eventually comes back and car drives as normal, but obviously lights stay on until the car is switch off again. I'm not convinced its the ALB sensor as 830 is within spec I believe.

I had a similar problem when I first bought my car back in 1993 but it was triggered by a strange occurrence. Whenever I ran over one of those botz dots on the road, in California these are used as slightly raised lane markers, it would trigger the ABS light then the TCS would activate and reduce power temporarily and then then the TCS light would come on as well. It still drove OK but since the car was new to me, I was a little concerned. Took it back to the dealer and they changed the TCS control unit behind the driver. They got a new one from Honda-USA which was reprogrammed to be less sensitive to road bumps of all types. Never had a problem since. You might try to see if the TCS unit has the latest programming updates. If you don't have access to checking that, try changing the TCS control unit out with a known good one from a friend and see if the problem stays or not. I would also disconnect the connectors and put them back in at all points just to reduce the chance of corrosion on any contacts within these connections. Remember gentlemen are cars are getting up there in age and that also means possible corrosion on connectors which can wreak havoc on computer inputs and outputs. JMO-ICBW
