U3485 OBD-II Diagnostic Network (U) Trouble Code Description

U3485 engine trouble code is about Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical. Fuel Temperature Sensor B Circuit Range/Performance and Cylinder 1 Injector Circuit Low causes most of code U3485.

Reason For U3485 Code

The reason of U3485 OBD-II Engine Trouble Code is Fuel Temperature Sensor B Circuit Range/Performance.

U3485 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The engine error 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 Repair U3485 Code

Before starting let's see U3485 repairing process steps:

• Qualified technicians will begin by using a scan tool to access U3485 code stored in the ECU.
• Technicians will note U3485 code present and any freeze frame data associated with them.
• After all, if you sure the engine trouble is finished, the code will be cleared.

The reductant injector is part of the system that reduces the gas that is expelled through either the catalytic converter in gas engines, or the particulate filter in diesel engines. There are sensors in the exhaust system, used by the reductant injector to input voltage readings to the PCM.

If you suspect that your car has a defective mass air flow sensor, bring it to a certified mechanic so that a whole computer diagnostic can be run. In most situations, a defective mass flow sensor has a certain code that will process throughout computer diagnostics, and is normally simple to check into with computer testing equipment.

Sometimes U3485 code comes with U348500 code.

Diagnosis Of Engine Error OBD Code U3485

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a U3485 trouble code to be stored

The first step is introductory and is about reacquiring all the canons that have been set. For this, the individual scanner will have to be plugged into the individual harborage of your vehicle. Make sure you indurate frame the data. Any canons that were set previous to the U3485 code will have to be sorted first, as they may have been the reason for the law to set in the first place. It's always good to rule that out.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
