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.
P1490-LOW SPEED FAN CONTROL RELAY CIRCUIT
With the ignition ON. Battery voltage greater than 10 volts .
An open or shorted circuit is detected in the radiator fan relay control circuit.
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.
- 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
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.
