Hey all, I’ve got a 2012 crv with 135k miles on it. Runs great. Never had any lights on my dash except recently- the VSA, AWD and EPS stayed on my dash (didn’t blink) . The car runs fine otherwise. Later in the day I drove it around and low and high speeds, the lights never came back on. I took it to get the codes checked and the code 27-21 “ steering angle sensor output signal malfunction” was present. Does anyone know what this means?
