Crank & Cam Angle Sensor Wiring | Shielded Cable Grounding
Summary
00:00 | - Dean Crawford has asked, what's the best way to wire a crank and cam angle sensor? Does the shielding need to be earthed on one side only and if so which side, the sensor side or the ECU side? This is a really good question Dean and we actually had some pretty big debate just recently on one of our Facebook posts. |
00:19 | In the automotive world it is essential when we are using shielded cable, to only ground that shield at one end. |
00:27 | Generally this will be done at the ECU header plug. |
00:31 | Now if we ground both ends, the problem with this is we can create what's referred to as a ground loop which can end up causing havoc with the operation of our ECU so we don't wanna do that. |
00:43 | The argument here that we faced is that when we ground only one end of our shielded cable, is essence what we're creating is an area that can be prone to gathering up EMI or electromagnetic interference. |
00:56 | That's OK though because that's exactly what that shield is designed to do. |
01:00 | It's designed to take that electromagnetic interference and drain it down to ground, preventing it from getting into the signal conductors that are within that shield. |
