The oil pressure gauge on my 2004 Yukon Denali with 60k miles recently 0 PSI oil pressure. The engine runs fine and the "check engine" light did not come on. The oil pressure gauge is the only gauge in the cluster not working properly. My GMC dealer is telling me that the oil pressure is fine but the oil pressure sending unit is bad. They say the job is $500+ to replace the sensor unit because they have to remove the intake manifold to replace the sensor. Does this make sense?
have the same problem?
