Test 70B - Open Oil Pressure Switch Sense Circuit
WARNING: This page is about a different car, the 1997 Eagle Vision, 1997 Dodge Intrepid, 1997 Chrysler LHS, and 1997 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST 58A
before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
. For wiring schematics, see WIRING DIAGRAMS
in this article. Perform TEST VER-1 - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Disconnect oil pressure switch connector, located next to oil filter. Connect jumper wire between ground and terminal No. 2 (Gray wire) on oil pressure switch connector. If oil pressure warning lamp illuminates, replace oil pressure switch. If oil pressure warning lamp does not illuminate, go to next step.
- Leave jumper wire connected. Disconnect instrument cluster Gray connector. Using scan tool in ohmmeter mode, measure resistance at terminal No. 5 (Gray wire) on instrument cluster Gray connector. If resistance is 5 ohms or greater, repair open Gray wire. If resistance is less than 5 ohms, go to next step.
- Remove and inspect oil pressure warning lamp. Replace lamp if necessary. If lamp is okay, repair or replace instrument cluster as necessary. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section.
