Where are the knock sensors on a V8?

RESISTANCE SPECIFICATION: The resistance specification of knock sensor 1 is 93 to 107 K Ohms. Place your multimeter in Ohms mode. Disconnect the knock sensors jumper wiring harness . The knock sensors jumper wiring harness is located on the left side (driver side) of the intake manifold. See photo above.

Where is the jumper for the knock sensors?

Below are the circuit descriptions of the 2 wires of the knock sensors jumper wiring harness. The knock sensors jumper wiring harness connector is located on the left side (driver side) of the intake manifold. See photo 2 of 2 in the image viewer above.

Why are my knock sensors not working properly?

You can also conclude that there are no wiring problems with the knock sensors jumper wiring harness. If the engine is knocking (pinging), then this test result lets you know that the source of the problem is an engine mechanical problem. CASE 2: The resistance of knock sensor 1 IS NOT within the indicated range.

How to test a knock sensor on a multimeter?

TEST 1: Testing Knock Sensor 1 (Front Sensor) 1 1. Place your multimeter in Ohms mode. 2 3. Connect the red multimeter test lead to the male terminal that connects to the dark blue (DK BLU) wire of the connector. The DK BLU wire is 3 5. You should see a resistance value between 93 to 107 K Ohms on your multimeter.

What happens if a knock sensor fails on a Chevy Silverado?

Knock sensors play an important as well as essential role in your Silverado’s engine functionality, detecting any engine noises caused by early detonation and adjusting the ignition-timing accordingly. When a knock sensor fails, detonation is not properly regulated and serious engine damage can occur, leading to some very costly repairs.
