Question: Car is taking longer to turn over.

Car is taking longer to turn over. Diagnostic said Camshaft or Crankshaft Sensor. Replaced those and unhooked the battery for 10 minutes, but still have the same problems: slow turnover and Service Engine Soon light. Has anyone else had this problem?

Sounds like you need to take it back in and have the diagnostic codes read again.

There could be an additional issue or a problem with the repair previously done.

Disconnecting the battery does not necessarily reset the engine codes. You need to use an OBD2 scan tool

Our mechanic replaced them again, reset the engine codes, and started it about 15 times and it seemed fine. I drove it to the grocery store, symptoms returned, light came back on. O'Reillys scanned it and came up with p0725 Engine Speed Input Circuit malfunction.
