Detailed Description

Standard Ignition PS-159 is an engine oil pressure switch designed around a blade-style terminal connection and a single-terminal layout for straightforward electrical interface. This part cross-references 18-1984 and OP6068 for the same application. It is a fitment-based replacement for Saab 9-3, Saab 900, and Saab 9000 models across the listed years, making it a practical match when servicing the oil pressure warning circuit on these vehicles.

For buyers searching for a Saab 900 oil pressure switch, Saab 9000 engine oil pressure switch, or a 1999 Saab 9-3 oil pressure switch, PS-159 provides the catalog-specific reference needed to match the application accurately. The 1986 Saab 9000 listing includes a spade terminal and light note, so connector style should be verified against the original unit before installation.

Common Issues This Part Addresses

• Oil pressure warning light staying on or behaving inconsistently
• Faulty oil pressure signal to the dash warning system
• Electrical connection problems at the pressure switch terminal
• Replacement need during engine service or sensor diagnosis
• Incorrect part matching when servicing Saab oil pressure circuits

Installation Notes and Tips

Confirm the original connector style, terminal layout, and vehicle application before installation. Inspect the harness connector for corrosion, looseness, or damaged terminals, since a poor electrical connection can affect oil pressure warning operation. Verify the replacement against the removed switch and the vehicle’s service information for the listed Saab model and year.
