P0199

DTC P0199, sometimes indicated as P019900 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing engine oil temperature sensor intermittent.

There are a few things that could cause this code: a faulty oil temperature sensor, a wiring issue, a bad ground, or a problem with the engine oil itself. If the code is recurring, you'll need to troubleshoot the issue to find the cause. If the code is a one-time event, you can clear it and see if it comes back.
