Cam Position Sensor, motor swap

[Kaiju Senso]

I'm still working on my Fiero motor swap to a 2005 Equinox 3400 (LNJ) using previous 3100/3400 parts and computer. Some have told me the cam position sensor isn't compatible with the older computer so I planned to just swap out the LNJ sensor for an LA1 sensor. Well after pulling out the LNJ sensor, it doesn't seem that easy. Here is my sensor.




So now I'm worried that I can't just bolt in the LA1 sensor. Do I need to swap the entire cam? Does anyone have any thoughts on this?

what computer are you going to use?

the plan was to use the wiring harness, PCM and fuel rails from a 98 3100 (monte carlo)

Your LA1 sensor should work fine in there...

Ok so it is that simple? I'm not quite sure how the sensor works and it looks like it reads the cam via direct contact. Is this the same issue people have overcome in their 3500 swaps?

[Superdave]

Most (about 95%) of the 3400 and 3500 swaps into older cars are done using the older OBD1 computers that don't need the cam position sensor. I remember a topic from about a year ago where we discussed this same thing for a OBD2 swap though.

The 3500 uses the same sensor you posted a picture of, it looks different than the older version but is the same length, has the same angle and mounting orientation as the older solid looking ones. Your old sensor will still read the trigger on the cam the same way.

Thanks a lot for your help
