How to test Toyota p0330 knock sensor codes?
Use a baer copper wire so you can get your test probe on it. Don’t short out the wires. Then put your multimeter on an AC setting and see if there is about 250mV or so. If you have a scope, that would be even better. 7.1KHz is a low frequency, but just see if you’re in the ballpark on both sensors.
When does the p0325 knock sensor code show up?
Now I get P0325 after about two hours of the car running. Since I commute about an hour, it happens halfway through the way home from work. ( I reset the code when I get home) A cold start, followed by an hour of freeway driving, followed by a cold start hours later, then about 30 minutes on the rode and the code will show up.
