What is typical cost to replace knock sensor?

Asked by Mar 20, 2016 at 05:47 PM about the 2002 Toyota Highlander Base V6 4WD

Question type: Maintenance & Repair

Check engine light on with code P0330. Dealer quoted price of just over $900.00 to replace malfunctioning sensor, but recommended replacing both at cost of about $1140.00. Seems high to me.

It's a bear to replace, but shouldn't be that much. Dealerships always charge more. Find some independent mechanics and get some quotes.

My local mechanic quoted me $1100, which included replacing both sensors and wire harness. Labor would be $400.

All, I just did this today on a 2011 Honda Pilot. It took some time, but it was a very easy repair. I replaced both the sub-harness ($11 at Honda) and the sensor ($20 at AutoZone). Turned out that mice ate the wire, so I am glad I bought it. I spent about 30 minutes figuring out how to "fish" the sensor out without removing the intake manifold. I did not have to remove the intake. I took off the upper intake plenum and the injector bank on the front side of the car. Used a 27mm thin-walled, short-well socket with a u-joint. I needed an extra 1/4" clearance for the connector to go through the socket so I used duct tape to hold the socket to the u-joint with the U-joint just barely in the top of the socket. Scott
