Thanks Dennis.

The alternative cam position sensor arrived today. Had to make some modification to it so it would fit in cylinder head in place of the OEM stock sensor. Here it is beneath the OEM sensor:

Fit was identical to the OEM sensor.

Same 1mm camshaft reluctor wheel clearance as with the OEM sensor.

Did some bench testing by installing in a head and turning the cam by hand and it generated the same signal output as the OEM sensor.

Facing slot

Facing wheel

Looking very promising so far. Next up full scale testing in the car.

Sweet! Another critical LT5 part well on the way to being solved!
THANK YOU PHIL!

I am impressed and thankful for all the expertise and dedication for the sake of everyone that enjoys these cars. This is neat to see it come together. I hope you have good weather for testing.

Phil, Once again to the rescue of the LT5. Highly interested in the end result so I may replace the sensor in my LT5 while it's out of the car and prior to installing the cam covers.

Installed the alternative camshaft position sensor on my 94 Z this afternoon and it performed perfectly during garage running tests. Even disconnected the signal wire which immediately triggered code 31 cam sensor failure. Reconnected and all was fine again. Rainy weather here prevented a more thorough road test however, from what I've seen thus far I'm confident it will perform just as well as the OEM sensor.

Great news for my ailing Z

Jeff,
Thanks for the offer. In the meantime Dave got me straightened out on the Metri-pack connector components I needed which are now on order and should arrive by Wednesday.

Fantastic job, Phil!
So, which model is this sensor originally listed for? Another GM model?

Jagdpanzer · 12-24-2017

It’s an generic aftermarket piece I found with a form close enough for replacing the OEM sensor.
Modifications:
• Machined spacer ring for adapting the sensor to the cylinder head mounting bore location.
• Correct size O-ring
• Machining O-ring groove
• Fabing up cable plug end
• Installing split wiring conduit
