DTC Confirmation Test
Malfunction is detected when improper voltage is sent to ECM from EVAP-CSPS. Depending on equipment available, use one of the following to set DTC:
- Using Scan Tool
Start engine and warm to normal operating temperature. Measure voltage between ground and ECM harness connector terminal No. 60 (fuel tank temperature sensor) by backprobing. See Figure. Ensure voltage is less than 4.2 volts. Turn ignition off and wait at least 5 seconds. Start engine and wait at least 20 seconds. Select MODE 7 on scan tool. - Using MIL

Ensure voltage is less than 4.2 volts. Turn ignition off and wait at least 5 seconds. Start engine and wait at least 20 seconds. Turn ignition off and wait at least 5 seconds. Turn ignition on and retrieve DTCs using MIL. See SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - INTRODUCTION article.
