Dash light help.... - Honda Prelude Forum

So i recently got a '97 Prelude SH. The ATTS has been staying on from when i start the car to when i turn it off. Then in addition to the ATTS light the brake light started to come on, it appeared to come on when i pushed hard on the brake pedal, then turn off. now its on from start to finish like the ATTS. then on the way home today the ABS light came on when i was accelerating hard up and through 3rd. so now all three lights are on ATTS, Brake, and ABS. can anyone tell me what could be causing each light and if they might be connected?? and what i can do to try and fix these problems? i got the day off tomorrow and could try and fix but i just need to know what i'm looking for. also would a OBD2 check engine computer be able to check these lights?? thanks everyone for their insight in advance

Yes, take it somewhere to have the codes pulled or pull them yourself. Use this method: Another DIY ATTS, ABS, & CEL (Check Engine Light) DTC

Post back what the codes are or download the service manual from the link below to figure out what they mean.

thanks for this method of pulling codes.

so the ABS was code 12 - Wheel Sensor: RF (Electrical Noise/Intermittent Interruption) i cleared it using the method on that same post. and the light hasn't come back on.

yesterday the ATTS was code 61 - Left Oil Pressure Sensor tried to clear it, but i was unsuccessful. today the code is 64 - Right Oil Pressure Sensor

Also today the CEL came on its code 61 - Primary Oxygen Sensor - P0133 (slow response), P1149 (range/performance), P1163 (slow response), P1164, P1165 (range/performance)

One of my friends said that i need two sensors for the left side of the ATTS. he said it was number 11 and 12 on the Honda ATTS diagram. I don't know what that means. he also said that they are the only two sensors with an (L) on them. So what do i need to do to fix the problems causing the lights??

This is what he meant: Honda Automotive Parts

You need to replace the oil pressure sensors on the ATTS unit, your oxygen sensors, and if the ABS light comes back you need the respective wheel sensor.

I don't really see a need to replace both oxygen sensors if the secondary isn't throwing a code. Even though it's only a $55 part and will have to be replaced eventually.

A quick easy troubleshooting step would be to swap the sensor positions (1 ~> 2, 2 ~> 1) and see what codes pop up.

As for the oil pressure sensors, I'd try clearing the ATTS codes again and see what comes back. Those ****s aren't cheap and functional used ones are tough to come by.

And you're welcome for that thread.

Tried to reset the ATTS again but still didn't work, tried multiple times. The code its spitting out has changed again, now its back to 61.

The ABS hasn't come back on, Knock on wood. And the CEL light has sense gone out, didn't reset it, it went out on its own.
