Mitsubishi Spyder U3488 code applies to vehicles equipped with dual clutch adaptive transmissions, automated manual transmissions, manual transmissions and automatic transmissions. Technicians also report the presence of excessive corrosion in the sensor connector as the cause of this code being stored.
Common Symptoms For Mitsubishi Spyder U3488
The PCM then compares input speed data with output speed data to determine shift patterns, as well as certain engine drivability functions. The typical input/turbine speed sensor uses a three-wire connector but check the vehicle manufacturer's wiring diagram to confirm the specific design of the vehicle in question
If the resistance level does not decrease with heat and increase as it cools, replace the sensor. If everything has checked out thus far, turn the key to the "ON" position and test for the presence of a voltage (and a ground signal) at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
Intermittent conditions can prove to be quite a challenge to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can be made. If the fuel shutoff valve has not been deactivated by a collision, use the digital volt/ohmmeter to test voltage and ground signals at the valve itself
If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)

Mitsubishi Spyder U3488 Troubleshooting
Having one of the signs of a bad gasket is usually not enough to prove a failure of a gasket, but multiple symptoms are most likely the result of gasket failure. It is advisable to have the vehicle driven as little as possible whenever the symptoms occur. Depending on the symptoms, either have the gasket replaced or repaired. The cost of replacing a gasket usually varies from one mechanic to the other. Replacing a gasket is quite expensive in modern engines due to their location and the amount of labor that is required to replace them. Mitsubishi Spyder U3488 OBD2 reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
How to turn off Mitsubishi Spyder U3488 check engine light ?
There are two ways to turn off the check engine light:
A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
