I've been trying to figure out a misfire/crappy running problem, and I finally got it scanned. Here's all the codes I got.

P0154
02 Circuit-No activity detected (Bank 2, sensor 1)

P0160
02 Circuit-No activity detected (Bank 2, sensor 2)

P0140
02 Circuit-No activity detected (Bank 1, sensor 2)

P0335
Crankshaft Position Sensor A Circuit

P0336
Crankshaft Position Sensor A Circuit
Range/Performance

Now, my question, does that just mean my crankshaft position sensors are bad/missing/unplugged? Where are they located?

By the way, this is a 94 Corvette LT1, in a 96 Trans Am. I used the T/A wiring harness, and it's still OBDII.
I'm wondering if maybe the sensors are different between the motors.. Anybody know?

No activity is when the sensor is not hooked up or the wireing is bad. The crank position code is well just that. Is it hooked up? Is the wireing good? It is also a early indicator that the opti is starting to have some issues.

I didn't think 94 LT1s had crank sensors. The sensor is located at the bottom of the timing cover, if you have one.

You will need to tune those codes out as the 94 does not have the sensor unless you installed the 95- cam and 96- front cover with sensor and opti.

I have done a few of these swaps hit me up if you want
