Code 46, Power Steering Pressure Switch, "A" Body: Notes

1992 Chevrolet Cavalier RS, 2D Convertible, 3.1 T, StandardSECTION Notes
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1992 Pontiac Grand Am, 1992 Oldsmobile Cutlass Cruiser, 1992 Oldsmobile Cutlass Ciera, 1992 Oldsmobile Achieva, and 1992 Buick Skylark. However, it is still accessible from the selected car via links, so may be relevant.

Power steering pressure switch is normally open. Turning steering wheel increases pressure and closes switch, pulling voltage on switch circuit low. Code 46 will set when power steering circuit voltage is low (indicating high pressure) and vehicle speed is greater than 40 MPH. Both of these conditions must be met for more than 15-25 seconds.

NOTE: Test numbers refer to numbers on diagnostic charts.
  1. Tests for normal operation of power steering switch. "Scan" testers will display this information differently. Refer to manufacturer operating manual for additional information.
  2. If display does not change to normal (no pressure) when switch connector is removed, check for power steering switch signal circuit shorted to ground. If circuit is not shorted, ECM is faulty. If display changes to normal when switch connector is disconnected, switch is defective.
  3. Determines if fault is switch or circuit. A jumpered connector should cause high pressure to be displayed, indicating wiring and ECM are okay. If high pressure is indicated and Code 46 is present, switch or switch connector is faulty.
