MIL Comes On With DTC P1659 TSB 05-008
SYMPTOM
In cold temperatures, the MIL comes on with DTC P1659 (electronic throttle control system control relay OFF malfunction). PROBABLE CAUSE Moisture inside the throttle control relay may freeze. This would cause the relay to fail, storing DIG P1659 along with any of these DTCs: P0135: Rear Air Fuel Ratio (A/F) Sensor (Bank 1, Sensor 1) Circuit Malfunction, P0141: Rear Secondary Heated Oxygen Sensor (Secondary HO2S, Bank 1, Sensor 2) Heater Circuit Malfunction, P0155: Front Air Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) Heater Circuit Malfunction, P0161: Front Secondary Heated Oxygen Sensor (Secondary H025, Bank 2, Sensor 2) Heater Circuit Malfunction, P0498: Evaporative Emission (EVAP) Canister Vent Shut Valve Control Circuit Low Voltage. CORRECTIVE ACTION Replace the electronic throttle control relay, the air/fuel sensor relay, and the starter cut relay.
