DTC P1288: Short Runner Solenoid Circuit: Description

Short Runner Valve (SRV) solenoid circuit voltage is monitored with ignition on and battery voltage more than 10.4 volts. To maximize engine performance, SRV system operates under Wide Open Throttle (WOT) conditions with engine speed at more than 5000 RPM. When actuated by PCM, SRV solenoid is actuated and allows mechanical linkage to redirect airflow to 6 short runners. DTC will set in Powertrain Control Module (PCM) memory when PCM senses short runner valve solenoid circuit is not in expected state. Possible causes for DTC to set are: defective SRV solenoid, defective PCM, defective connector or defective wiring.
