Keep your power steering system talking to the engine with the Standard Ignition Power Steering Pressure Switch PSS19. This switch senses hydraulic pressure in the power steering circuit and signals the engine control system to adjust idle when steering load rises during low-speed and parking maneuvers, helping the engine compensate for the extra pump load. It installs as a direct-fit replacement for a wide range of Nissan applications, including the 1995-1998 200SX, 1989-1990 and 1994-1998 240SX, 1984-1989 300ZX, 1990-1994 Axxess, 1986-1994 D21, 1985-1994 Maxima, 1987-1996 Pathfinder, 1995 Pickup, 1987-1989 Pulsar NX, 1993-1998 Quest, and 1986-2001 Sentra — see the Buyer's Guide tab for the full list and engine-level details.
If a failed pressure switch is the cause of erratic idle or a stored power steering code, this replaces it.
