Engine missing something

[BasedKami]

Hi all,

Got this 95 GST recently and have noticed that it seems like some sort of sensor was eliminated from the valve cover, the first image is my vehicle and the second is a picture I found on google with what looks like is supposed to be located there.

Could anyone tell me what that is?

10-4, thanks for the quick reply,

Any idea why the heck they would've removed it?

It may be running a crank trigger. Any extra parts on the timing side?

I’m a 1g guy so my knowledge on 2g is very limited but to my knowledge they have a crank trigger sensor at the crank instead of the cam angle sensor and is controlled by the ECU instead of with the cam.

This is what google had to say about it.

“
A 2G DSM (1995–1999 Mitsubishi Eclipse, Talon, Laser) uses a separate crankshaft position sensor (often called the crank angle sensor) located near the oil pump on the front crank trigger plate, distinct from the camshaft angle sensor. [1, 2]

Function and Location

• • Crankshaft Sensor (CPS): Mounted at the front of the engine behind the lower timing gear/crank pulley, reading the trigger plate (sensing blade). [1, 2]
  • Camshaft Sensor (CAS): Location varies by year; 2GA (1995–1996) models have it behind the intake cam gear, while 2GB (1997–1999) models have it on the driver's side end of the cylinder head like a 1G. [1, 2]
  • OEM Availability: Genuine factory sensors (such as OEM part MD300101) have largely been discontinued by Mitsubishi, leading many owners to source replacements or convert to alternative setups. [1]

Common Issues and Solutions

• • No-Start / Cranking Without Spark: A failed crank sensor stops the engine from firing or injecting fuel. [1]
  • Wiring Breakages: The harness near the front crank angle sensor is prone to oil contamination, melting, or brittle wires. [1, 2]
  • 6-Bolt Swaps: Swapping an older 6-bolt 4G63 engine into a 2G chassis often eliminates the stock lower crank sensor, requiring a 1G style CAS conversion or specialized trigger setups like those from Kiggly Racing. [1, 2]
  • 1G CAS Conversion: Many tuners adapt a 1G in a 2G - Magnus Motorsports style cam angle sensor configuration using an adapter harness and tuning software to invert or manage the signals. [1, 2, 3]
  • Explore an adaptation guide from Magnus Motorsports. [1]
  • Review standard trigger configurations at Kiggly Racing. [1]

95 and 96 dont have the cam sensor there. Its under the intake cam gear and there is a crank sensor also. What you have is stock and correct for a 95.

Almost forgot there is a bracket that goes across the seal and you are missing that.

Thanks @pauleyman

Thanks Pauleyman! Good to know
