    SYMPTOM
    P1495-LEAK DETECTION PUMP SOLENOID CIRCUIT

    WHEN MONITORED
    Immediately after a cold start, with battery/ambient temperature between 4.4 °C (40 °F) . F and 32 °C (90 °F) . Coolant temperature within -12 °C (10 °F) of battery/ambient

    SET CONDITION
    The state of the solenoid circuit does not match the PCM's desired state.

    POSSIBLE CAUSES

    • Wiring Harness Intermittent
    • Leak Detection Pump
    • Fused Ignition Switch Output
    • LDP Solenoid Control Circuit Shorted To Ground
    • LDP Solenoid Control Circuit Open
    • PCM

    Leak Detection Pump System
    The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

    SYMPTOM
    P1490-LOW SPEED FAN CONTROL RELAY CIRCUIT

    WHEN MONITORED
    With the ignition ON. Battery voltage greater than 10 volts .

    SET CONDITION
    An open or shorted circuit is detected in the radiator fan relay control circuit.

    POSSIBLE CAUSES

    • Low Speed Radiator Fan Relay Intermittent Operation
    • Intermittent Condition
    • Fused Ignition Switch Output Circuit
    • Low Speed Radiator Fan Relay Resistance
    • Low Speed Radiator Fan Relay Control Circuit Open
    • Low Speed Radiator Fan Relay Control Circuit Short To Ground
    • PCM

    P0700
    Notes
    The Transmission/Transaxle Controller monitors the malfunction of sensors and actuators relating to Transmission/Transaxle Control. If any malfunction is detected, they inform the PCM by sending a signal - By illuminating the MIL and by setting the P0700 code.

    P0700 means that a code has been set in the Transmission/Transaxle Controller.

    This code is for information ONLY.

    If P0700 is present, check for Transmission/Transaxle codes.
