16711 - P0327 - Knock Sensor 1 Circ Low Input
I went on a recent road trip, and filled up on some shady gas. Immediately the MIL tripped but I didn't have my vagcom on me. Once I used the crappy gas, I filled again with some V-power and the MIL went out, only to come back after the next refill.
A day later I got the car home and scanned -
16711 - P0327 - Knock Sensor 1 Circ Low Input - Intermittent
Does this mean the car actually knocked, probably due to the crap gas? Or is this an indication of sensor malfunction? Which knock sensor is Circuit 1, and where is it located?
Will I need a multi-meter to diagnose?
