should be actuated when pressure is 218-290 psi. Gradually open shutoff valve to decrease pressure. Check pressure when PSP switch is de-actuated. PSP switch should de-actuate at 102-174 psi. Turn engine off. If PSP operates as specified, go to next step. If PSP does not operate as specified, replace PSP switch. Go to step 8). 5) Disconnect PSP switch connector. On 3000GT, go to next step. On Montero, turn ignition off. Disconnect PCM connector. Ground PCM connector terminal No. 54. Using DVOM, check continuity between chassis ground and PSP switch connector terminal No. 1. If continuity does not exist, repair wiring harness as necessary. If continuity exists, go to next step. 6) Turn ignition on. Using DVOM, check voltage between ground and PSP switch connector terminal No. 1. If battery voltage does not exist, replace PCM. If battery voltage exists, go to next step. 7) Road test vehicle and attempt to duplicate conditions that caused original complaint. Recheck for DTCs. If no DTCs are displayed, test is complete. DTC P0705: TRANSMISSION RANGE SENSOR CIRCUIT FAILURE DTC P0705 is related to automatic transmission diagnostics. For diagnostic procedure, see TRANSMISSION SERVICE & REPAIR article. DTC P1103 & P1104: TURBOCHARGER WASTEGATE SOLENOID CIRCUIT FAILURE NOTE: This test applies to 3000GT with turbocharger only. For terminal identification, see TERMINAL IDENTIFICATION. For circuit and wire color identification, see L - WIRING DIAGRAMS article. 1) If using scan tool, go to step 7). Remove vacuum hoses from turbocharger wastegate solenoid. Disconnect solenoid harness connector. Connect a vacuum pump to solenoid nipple "A". See Fig. 46. Go to next step. 2) Using jumper wires, connect battery voltage and ground to solenoid terminals. Ensure vacuum does not hold with nipple "B" unplugged, and negative jumper wire connected. If solenoid does not test as specified, replace solenoid. If solenoid tests as specified, go to next step.
