Pulsed Secondary Air Injection (PAIR) System

Remove PAIR solenoid valve (located at left front of engine). Connect hand-held vacuum pump to solenoid valve nipple. Apply vacuum to solenoid valve. Vacuum should hold.
Apply battery voltage to terminals of solenoid valve. Vacuum should bleed down when voltage is applied to terminals. Using an ohmmeter, check resistance across solenoid valve terminals. Reading should be 33-39 ohms at 68°F (20°C). If reading is not within specification, replace valve.
Turn ignition on. Using DVOM, measure voltage at harness connector terminal No. 2 (Black/White wire). If battery voltage is present, go to step 4). If battery voltage is not present, check and repair circuit between PAIR solenoid and ignition switch.
Disconnect PCM harness connector. See POWERTRAIN CONTROL MODULE (PCM) LOCATION table under COMPUTERIZED ENGINE CONTROLS. Connect jumper wire between PCM terminal No. 60 and vehicle ground. See Figure .
Using DVOM, check for continuity between harness connector terminal No. 1 (Red/Yellow wire) and vehicle ground. If continuity does not exist, check and repair circuit as needed. If continuity exists and preceding tests do not show any system or component malfunction and PCM is suspected, substitute PCM with known good unit and retest system.
