carfreak85 Posted October 26, 2015 Share Posted October 26, 2015 Has anyone ever had this sensor fail? I was playing around with an SSM2 tool and after running a diagnostic on my brake system, it returned this message: 42 - G sensor high friction detected The only reference I can find for this code on NASIOC is the "How to read brake codes" thread, but it doesn't go into any more detail than how to pull and decode the codes. Is this one of those codes that will show up when the car is turned off but goes away when you are driving? Anybody replace their G-sensor before?

987687 Posted October 26, 2015 Share Posted October 26, 2015 If you rub the belly of the car just right you might find the G-sensor Quote Link to comment Share on other sites More sharing options...

Fairtax4me Posted October 27, 2015 Share Posted October 27, 2015 High friction detected? Maybe it got some dust in it somehow? Is the ABS light on? Might just be a code that pops up when certain tests are performed? 1 Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted October 27, 2015 Author Share Posted October 27, 2015 No ABS lamp. Heck, I don't even know where the G-sensor mounts on a GD or what it looks like. Guess I'll have to ask at the dealer... Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted October 27, 2015 Share Posted October 27, 2015 There's a Yaw/roll sensor under the center console IIRC. That may be what this code refers to, but I'm not positive of that. If the lamp works, but isn't normally lit, and the ABS system works normally, I wouldn't worry about it. 1 Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted April 22, 2019 Author Share Posted April 22, 2019 @GeneralDisorder You ever run into this before? Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted April 22, 2019 Share Posted April 22, 2019 (edited) just doing a general search, there's more info on it as a definition for an idle switch or TPS-related code if it is a '42' blink-code. here's a FSM page about it; https://legacygt.com/forums/showthread.php/check-engine-code-42-217170.html but, if OBDII - P0042 is an oxigen sensor heater circuit. what car?

carfreak85 Posted April 22, 2019 Author Share Posted April 22, 2019 This code was pulled using a SSM2 in the "Brake" diagnostics. This isn't an engine related code, this came straight from the ABS computer. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted April 22, 2019 Share Posted April 22, 2019 ah, that definition seems to be voltage-related in some posts - maybe check connections and ground wires? found this; and https://www.subaruoutback.org/forums/66-problems-maintenance/29113-abs-code-42-a.html Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted April 22, 2019 Author Share Posted April 22, 2019 I don't get a lamp for this code, but noticed a code for the brake system last time I had the SSM2 hooked up, pulled the code and it was "42 - G sensor high friction detected." Did a quick read of those threads. I'll look for a rusty relay, but I'm not missing a tone ring and the code "42" appears to have been given a different function in the 2002 WRX compared to the threads you linked to, which mention "low voltage" as pertaining to code 42.

GeneralDisorder Posted April 23, 2019 Share Posted April 23, 2019 I have never had that come up on any car I've scanned. Very strange. GD Quote Link to comment Share on other sites More sharing options...
nipper Posted April 23, 2019 Share Posted April 23, 2019 Its the G sensor under the center console in the center of the car. It measures the acceleration/deceleration of the car. Its reading high, you did something to scare all the G's out of it. 1 Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted April 23, 2019 Share Posted April 23, 2019 ^^^ what he said There may be some kind of calibration required if the unit is replaced - maybe the FSM has info on that? 1 Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted April 23, 2019 Author Share Posted April 23, 2019 I'll have to look into the FSM, I don't think the module has ever been replaced, we've owned the car since new. We did have the ABS reflashed with the updated code all those years ago, which I'm regretting now, noticing how even the slightest lockup will send the ABS system into convulsions...

nipper Posted April 23, 2019 Share Posted April 23, 2019 So this has absolutly nothing to do with the telephone shaped dent in the front of the car Quote Link to comment Share on other sites More sharing options...

I cant get a straight answer on that. But the first step would be to unplug it then replug it in and see if thats enough action to clean the contacts. 1 1 Quote Link to comment Share on other sites More sharing options...
