Genuine GM early style LS Oil pressure sender. After years of testing the “Other brands” and we have found that none are as reliable as the OEM Genuine sensor. These sensors are the true way to tell accurate oil pressure on your LS Vehicle. If your engines oil pressure screen reads 894kps, replace this sensor, if your oil pressure reads low (below 170kpa oil pressure), it doesn’t hurt to replace this sensor to verify that reading. Test should be carried out with 10w40 or 5w30 oil at 100deg c oil temp.   Suit the Following Models1999 -2005 VT-VZ 5.7Lt  LS12005-2007 VZ 6.0Lt L76/L98/LS22006-2009 VE 6.0Lt L76/L98/LS2/LS3 up to VIN tag ending 9L300000
