What are the Denso sensors on a Lexus ES300?
At least not electrical signal parts. I purchased two Denso sensors on Amazon and made sure they had the same markings as the original that came out of the car. It took another 6 hours to tear the intake manifold out and replace the Import Direct sensors with the Denso sensors.
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.
