resistance can be deceiving ...... Posted by jak [Email] ![]() ![]() In Reply to: Re: Did you check your front O2?, a12, Tue, 20 Nov 2007 17:02:43 Members do not see ads below this line. - Help Keep This Site Online - Signup |
do live circuit loaded voltage drop testing its the only way to go
turn on everything & I mean everything.......
with the engine running bridge say the negative battery terminal with sensor grounds using a DMM set to volts DC I if you get anything over like 1/2 volt you work the ends toward each other till you isolate the resistance problem
you can bridge the engine block to sensor ground or whatever you want to bridge to make sure there are no drops
do the same on the power side or refrence+
often resistance will be fine untill you load the circuit & then the problem shows its ass
happy thanksgiving
