RE: Testing Knock Sensors

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

... I don't know that there is much you can do to test it ... about the only
things you can do that I'm aware of are to make sure that it is tightened to
the proper torque and that the connector on the firewall is making proper
contact.  I added the last note because the new sensors come with gold
plated contacts which indicates to me that there may have been a problem
with noisy connections with the old connector.  If after you do these things
you still get the code replace the sensor.  When I dealt with this on my '88
5kCSQA the code went away after I replaced the sensor ...

HTH!
