Signal Waveform
Inspection 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Disconnect the fuel pressure regulator valve connector.
S
Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
