Power Steering Pressure Switch

ECM applies and monitors reference voltage to power steering pressure switch from ECM terminal A6 on Sidekick TBI or ECM terminal A19 on Sidekick MPI. ECM applies and monitors reference voltage to power steering pressure switch from ECM terminal B3 on Swift DOHC, and from ECM terminal A18 on Swift SOHC. On all models, when steering wheel is turned, pressure switch closes, pulling reference voltage low. ECM uses this signal to help determine control of Idle Air Control (IAC) valve.
