So, starting about 2 months ago my car started starting kind of hard and the CEL came on. It would crank for a few seconds, start to turn over but sound like it was going to sputter out, but ultimately turn over. It seemed to be exacerbated the longer the car sat between times running. I let the car sit for about a week while I was waiting for parts to come in to change out my front brakes, and now it won’t start.
I hooked up my newly acquired OBD II reader and got the following DTCs:
P0130 - O2 Sensor Circuit Malfunction Bank 1 Sensor 1
P0130 P - Same, P for Pending
P0336 - Crankshaft Position Sensor A CKT Range/Performance
P0340 - Camshaft Position Sensor A Bank 1 Circuit Malfunction
Based on my limited understanding, I would think something having to do with the last two codes would be why the car isn’t starting, but it seems like it could also easily be something else not directly indicated by those codes. So what I’m wondering is, do I need sensors replaced, or is there something else that needs replaced on the car.
I am kind of pig-headed and would like to fix it myself, but maybe its something beyond my ability. If it makes a difference, the car has ~130k on the odo.
