DTC Confirmation Test

Malfunction is detected when improper voltage is sent to ECM from EVAP-CSPS. Possible causes are:

• EVAP-CSPS circuit open or shorted.
• EVAP-CSPS hose plugged or leaking.
• Defective EVAP-CSPS.
• Defective EVAP-CVCV.
• Defective EVAP-CPVCV.
• Defective EVAP canister.
• Hose between EVAP canister and water separator plugged or leaking.

To set DTC, start engine and warm to normal operating temperature. Measure voltage between ground and ECM terminal No. 92 (fuel tank temperature sensor signal) by backprobing. See Figure and Figure . Ensure voltage is less than 4.2 volts. Turn ignition off and wait at least 10 seconds. Start engine and wait at least 20 seconds. Select MODE 7 with scan tool.
