Have a 2010 Chevy equinox. The Traction control and stabilitrak warning lights are on, with no check engine light coming on? Obviously not able to have a diagnostic ran at auto zone/O'Reilly. Just recently had power steering fluid cooling pipe replaced (it needed to be, was hanging from the bottom of the engine) power steering pump seems like it's working well! Power steering works, engine sounds great, starts up fine, doesn't feel like it's lost power! Though the traction control light and stabilitrak warning lights are still coming on? I have a hum that reads and runs a diagnostic and sends alerts/info about the vehicle to my email... The last code that was read was Po18B... That is a fuel pressure Sensor B Circuit. Does this (FPS) and the traction control light and stabilitrak warning have to do with each other?
