Where is the vacuum gauge on the intake manifold?
To check manifold pressure with a vacuum gauge you need to locate a port on the intake manifold or throttle body. Manufacturer’s install ports on their manifolds for lots of different reasons: Brake Booster, PCV tube, EGR Switch, A/C vents, etc.
What does steady low mean on engine vacuum test?
Steady low between 5-10 “hg vacuum: This indicates that the engine has a leak in the intake manifold or the intake gasket. This leak should be easy to find because it would be making a loud hissing noise. Steady low between 10-15 “hg vacuum: This reading indicates late valve timing.
What should the vacuum be on a normal engine?
Normal Engine: On a normal engine, accelerate to around 2000 rpm and then quickly release the throttle. The engine should snap right back to a steady 17- 21 “hg vacuum. Steady low between 5-10 “hg vacuum: This indicates that the engine has a leak in the intake manifold or the intake gasket.
What does a vacuum test on a car mean?

What causes Hyundai Santa Fe to fail emissions test?
The Santa Fe’s ECM will trigger this code when it detects that the vacuum level in the Purge System is not within the proper specifications. P0441 can cause the vehicle to fail an emissions test.
What causes purge valve to fail on Hyundai Santa Fe?
When it fails, the purge valve will no longer be able to operate properly. When this happens P0441 will almost always throw. Bad Vacuum Line – If the vacuum line going to the purge canister has failed, that’ll cause the P0441 code to show up for sure. This is worth taking a look at especially if you live in a drier climate.
How do you do a vacuum test on an engine?
Engine Vacuum Test. To check manifold pressure with a vacuum gauge you need to locate a port on the intake manifold or throttle body. Manufacturer’s install ports on their manifolds for lots of different reasons: Brake Booster, PCV tube, EGR Switch, A/C vents, etc.
