Customer Question

My 2009 CRV check engine light is on and the "D" for Drive is flashing. I sense or hear no problem with the transmission. PO Code on my checker reads PO843. High pressure switch/sensor might be at fault. What do you think?

Most likely you have a bad second gear pressure switch. I have seen many of the pressure switches go bad.

The switch is located under the air cleaner assembly. The connector for it is grey.

This fault code does cause the "D" light to flash and check engine light to come on.
