Where is the jumper for the knock sensors?
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.
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.
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.
What does the p0332 knock sensor code mean?
P0332 -What Does It Mean? (1999-2006 V8 Chevrolet Silverado, GMC Sierra). When the knock sensor fails, the fuel injection computer will light up the check engine light with one (or both) of the following trouble codes: P0327 Knock Sensor No. 1 Circuit Problem.
Are there any knock sensor problems on GM trucks?
Knock Sensor Problems on GM Vehicles. Knock sensor problems are common on 1999-2007 Chevy Silverado, Express Van, Tahoe and Suburban trucks. Of course, this means that the GMC Sierra and Yukon of the same years have the same issues.
What are the codes for the knock sensor?
Eventually this turns on the check engine light and sets the codes P0332 and P0327. Note that often either one or the other code will set. Regardless if one or both codes are set, not only should the two original knock sensors be replaced, but you should also replace the harness.
Where are the knock and Ping sensors located?
It’s a piezoelectric automotive sensor that produces a small voltage signal when it hears internal engine noise that we often call knock and ping. This is why the location of the two sensors is a problem. In order to hear the engine noise reliably the sensors are buried under the intake manifold.
What is the spark knock code on a Chevy Tahoe?
Do you have a 1999-2007 Chevy Silverado, Tahoe, Suburban GMC Sierra or Yukon equipped with a 4.8, 5.3 or 6.0 Liter LS series engine and are experiencing an illuminated check engine lamp, a stored code P0332 and/or P0327 accompanied by spark knock? Watch this video for more information. Loading…
