My car has a bad Crankshaft position sensor. It's a 2005 chevy impala, 3.4 and I know there are two possible places where it could be. Can you tell me the exact place they would be located?
Do you
have the same problem?

Hello,

There are two crankshaft position sensors on this car one at the front of the crankshaft and the other on the side of the block which will need to have a relearn which I have included as well.

this guide will walk you through the steps with the instructions on how to change the sensor for your car below.

Welcome to the forum, I'm not sure of engine litre size? I looked at the 3.8L engine. I didn't notice a picture.

When car seems ready to shift to 2nd gear, it seems like there's an electronic "miss." Sometimes this happens several times in a row and then it runs normal. This started to happen after having the belt and pulley replaced in the fall. (May or may not be a coincidence.) Took it back to repair shop a couple of weeks later. They checked the computer system which read P0336 - replace crank sensor. They did. That seemed to eliminate problem until recently which is 4+ months later.

If the car has developed a engine miss under a load like you said, it could be related to the spark plugs, the spark plug wires, or the ignition module that controls the spark itself. I'd look into having a tune up done.
