Power Steering Pressure Switch Test
Disconnect switch connector. Switch is attached to power steering high pressure hose. Check resistance between switch connector terminals. On 300ZX, replace switch if resistance is not 2-3 ohms. On all others, start engine. Replace switch if continuity is not as specified in POWER STEERING PRESSURE SWITCH (EXCEPT 300ZX) table.
POWER STEERING PRESSURE SWITCH (EXCEPT 300ZX)
| Condition | Continuity |

| Steering Unloaded (Not Turning Steering Wheel) | No |
| Steering Loaded (Turning Steering Wheel) | Yes |
NOTE:
On Maxima, Pathfinder, Pickup 3.0L and 300ZX, perform Throttle Position Sensor (TPS) test at connector farthest from TPS, not at connector which terminates directly at TPS.
