checking ohms on a knock sensor 94 c1500 4.3.
ohmeter set on 200,000. resistance reads 8.5.
according to the book ohms should be between 1.5k and and 10k. to me looks to be within range. am i right. if i am why do i keep getting a code 43.
thanx in advance

Try getting a reading(power disconnected) with the setting lower, like 25,000 or 20,000 ohms.

Getting a reading that low on that high of a scale is like weighing a golf cart on a truck scale, it's just not going to be very accurate.

set it at 20,000 and got 8.25
