You will have to remove the intake manifold to gain access to the knock sensors. There are two sensors in the valley under rubber plugs. The sensor in the rear has a tendency to fill up with water and cause trouble. You have to make a dam with RTV to stop the water from getting in there.

Caution: Refer to Battery Disconnect Caution in Service Precautions.

  • Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure

  • Drain the engine oil and remove the engine oil filter. Refer to Engine Oil and Oil Filter Change

10. Remove the engine wiring harness retainer bolts from the engine oil pan.
11. Remove the engine oil cooler pipe to oil pan bolt.
12. Remove the transmission oil cooler pipe retainer and the bolt from the oil pan.

Installation Procedure

Important: The alignment of the structural oil pan is critical. The rear bolt hole locations of the oil pan provide mounting points for the transmission bellhousing. To ensure the rigidity of the powertrain and correct transmission alignment, it is important that the rear of the block and the rear of the oil pan must NEVER protrude beyond the engine block and transmission bellhousing plane.

My 1999 gmc yukon wont start code say p0336 just rotates


p0336 means CKP sensor performance error. Replace the crankshaft position sensor. If that doesn't fix the issue there is a number of GM factory service bulletins that point at a manufacturing problem with Yukon engine. Find the appropriate service bulletin for your engine in this page.

I have a 2003 yukon Problem with the GMC Yukon XL

What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .
