Condensor that grounds/bolts to clutch slave

[Pete_89T2]

There is square black condenser (capacitor) with a grounding lug that grounds to the engine on one of the clutch slave cylinder bolts. On mine, the wire broke off right where it goes into the condenser, so it can't be spliced/fixed.

Based on FSM schematics, I'm pretty sure this condenser is part of the oil pressure meter circuit - can anyone confirm?

If so, it's just there to shunt/ high freq. noise off of the oil sender's DC reading. Can probably live without it, but easy enough to fix by wiring in another 10 microfarad or so capacitor as a substitute for the stock part.

You are correct.
It is to minimize pulses from the oil pressure sensor to the oil pressure gauge in the instrument cluster.
Many times, it is broken or left disconnected - usually due to a clutch job and / or disconnecting the transmission from the engine.
I've never seen the stock oil pressure gauge "freak out" due to it not working.

Side note, there's another, identical cap located under the trailing coil pack.
That one is to minimize interference from the trailing coil pack switching between the front and the rear rotor for the ignition select.

Thanks Ted, that's what I thought. Being an EE, and reading the FSM schematic, I knew that one just served as a high-pass noise filter on the oil pressure circuit, but the FSM schematic doesn't always show physical locations of parts. Yeah, I can live without it there, I'll just leave it disconnected.

For those of you reading that are not electrically savvy, if this condenser breaks (one bolted on the clutch slave) DO NOT take the broken wire, slap a lug on it and reconnect it to ground - doing so would short your oil pressure sender to ground and screw up its reading.

I might have one lying around if I can find it I will send it if you want it.
