Wiring scamatic for tachometer

The most common repairs for a recurring P0335 code would be: replacing the crankshaft position sensor, replacing the ignition control module, finding and repairing a wiring concern. It is impossible to know what is going on without hands on troubleshooting. The code itself does not lead to what part or parts need to be replaced; in this case, it just states that there is a concern with the Crankcase Position A Circuit. You might find a wiring concern - is there any damage evident to wiring due to rodent activity in the vehicle? Replacing parts without testing often results in an ineffective repair attempt. https://repairpal.com/auto-repair-near-me
