How do you troubleshoot a crank sensor on a 2005 pt cruiser

Here's a LONG thread about p0340 codes on PT Cruisers. Hopefully, it will get you pointed in the right direction. https://www.allpar.com/forums/threads/chrysler-pt-cruiser-code-p0340.151113/

P0340 Chrysler - Camshaft Position Sensor Circuit Bank 1 Sensor 1 I would charge the battery with a low amp charger over night.
then check the Cam Position Sensor.
How to Test the Cam Sensor Chrysler 2 0L 2 4L

Check the timming belt. and give us more clues When did it stop running, while going 65 mph or what,

You may not believe what I am going to say, but pumping the gas pedal does nothing to make the engine start.
The throttle position sensor does not start sending a signal to the computer until after the engine starts.
However, cranking the engine for an extended period of time could have an effect. If the fuel pressure is low, cranking the engine would build it back up to normal.
I would suggest you have the fuel pressure checked before and after the first attempt of the day. The car would need to sit overnight for the first test.

they can run with out a cam sensor but they will not run with out crank signal i would check for crank signal it may not throw a dtc because it wont start.

intermittent crankshaft sensor

PCM detects an error when the camshaft position is out of phase with the crankshaft position

My thought is to get a refund from the shop that tried to replace parts in order to secure your problem. The job of the shop is to diagnose the problem, not to replace items that may be the problem. Chrysler Master Techs are not trained to just replace parts, they fix the problem by diagnosing it properly.

You need to see a Chrysler dealership so they can attach a DRBIII and tell you exactly what is at stake.

I hope this helps you. I would be mad as heck.

I would not think the plugs and wires would be the problem because they would all have to fail at the same time to provide the symptom you experienced.

1. Get your money back
2. DRBIII

change the crankshaft positon sensor in the rear of the engine above the oilfilter. Also check the wiring to this sensor, they have a problem shorting out. You have to change the camshaft and crankshaft sensors at the same time. Make sure you give your car a major tune up. Did you check yor starter?.........runjoe

the crank sensor is located on back right side of engine by were the trans. bolts up.is the no start when could or hot?

I think it sounds like your CAM sensor has fallen off or is faulty.

The computer controls the ignition timing and the injectors to squirt fuel in to the pistons at the right time. If the computer doesn't sense the cam angle correctly as you accellerate it can't put fuel into the pistons to match the opening and closing of the valves.

If you have a manual you can strip down the top of the engine to see the timing gears on the end of the Cam shaft and see if you can see the cam sensor and if there is anything obviously wrong (i.e. its missing) but you may be as well getting to the dealer to have it checked out and fixed. So the good Fuel pressure will not really effect the engine falling on its face as its a computer timing issue caused by bad sensor information that's causing the bad running.
