Check engine light out afer code addressed, comes back on afer engine kill and restart.

You need the transmission control module scanned for fault codes. I know the check engine light must be coming on when this happens, correct?

Have the codes read. Check the brake fluid level. Wouldn't surprise me if low brake fluid doesn't kill the engine know days.

this is normal practice to protect the engine /transmission from costly repairs. Run the fault codes to find which sensor is activated. Check all fluid levels (coolant at the radiator cap). Fix the fault and use a scanner to reset the light.

run fault codes and check for cam/ crank position sensor. Check that the cam shaft is turning. Check operation of the immobiliser system

That code dsoesn't 100% mean the sensor is defective, other factors can set it. See list below.
Possible causes- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0601 CHEVROLET - Power Control Module Internal Fault

Cause: Faulty PCM. (Powertrain control module)

check for stored codes by turning key as follows;
on is when the dash lights come on (no cranking) and off is one click back.

off-on off-on, off-on The codes will blink out on the check engine light in pairs, 5-5 being the end of the test. Or the codes will display on the digital odometer. write down the codes and report back or do a google search.

You need to replace the vehicle speed sensor located on the trasmission.

unplugged tha bettery few minutes;if the check light turn on again, you have any fault code there and needed scannign for know what code is. With this number code we can tell you other details.

Good luck.

Did you reset the code system? The error code does not reset itself.

1. AutoZone can reset it for you (free).
==== or ===
2. You can disconnect the negative cable from your battery for 10 minutes, it will reset the code.

3. The error will go away (for good, we hope).

Hope this helps!

You need to check the fuel injection system, throttle body, sensors, check harness for ground. Best solution is to have your engine scanned using Tech 2 scanner. The mechanic will advice you based on the scan code. Whenever the "service engine soon " light the computer system logs the error code. You can retrieve this error code using a scanner.
