P0295 Cylinder 12 Injector A Circuit High
Cylinder 12 injector A control voltage above expected range. A flow-deviating injector throws off cylinder balance — adjacent cylinders run leaner/richer to compensate, often masking the root cause until the trim limit is hit.
Is it safe to drive with P0295?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
