I have a P0320 code 2001 Mazda B4000

Question

I've changed the crankshaft position sensor twice and the engine speed sensor. It runs ok for half the day and then same problems. Any ideas. Thanks

HI there

Check the wiring, especially any grounds under the hood and on the engine. Poor grounds can cause voltage spikes and damage the sensors or cause issues with the voltage being sent to the computer on the signal lines.
