Common causes of Sta Matilde SM U3460 include four-wheel drive switch or actuator failures. Other causes include faulty sensors, solenoids, or switches, and defective wiring harnesses and connectors.
Common Symptoms For Sta Matilde SM U3460
The PCM then compares transmission output speed data with engine input speed data to determine shift patterns, as well as certain engine drivability functions. The typical output 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
A scanner (or code reader) and a digital volt/ohmmeter will be required to successfully diagnose this code. Virtually every vehicle (with an automatic transmission) produced since the mid-eighties is equipped with some type of computer controlled automatic transmission system
If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)
Ignition System Or Misfire
Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
Transmission Engaged At High Throttle Angle
Sta Matilde SM U3460 Troubleshooting
When you put your foot down on the brakes you expect your car to quietly slow down and come to a stop. The power your foot applies on the brake pedal is assisted by hydraulic pressure. Your foot's force engages a piston and caliper with brake pads attached (bonded abrasive and heat resistance metal or ceramic) to put pressure on the rotor. Sta Matilde SM U3460 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 Sta Matilde SM U3460 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.
