C1758 Code Meaning :

C
OBD-II Diagnostic Chassis (C) Trouble Code For Engine
1
Fuel And Air Metering
7
Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
5
Turbocharger Boost Sensor A Circuit Low
8
Timing Reference High Resolution Signal A Too Many Pulses

The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.

C1758 OBD-II Diagnostic Chassis (C) Trouble Code Description

C1758 engine trouble code is about Timing Reference High Resolution Signal A Too Many Pulses. Throttle/Pedal Position Sensor/Switch A Circuit Intermittent and Turbocharger Boost Sensor A Circuit Low causes most of code C1758.

Reason For C1758 Code

The reason of C1758 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.

C1758 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission in your car.

How To Repair C1758 Code

Before starting let's see C1758 repairing process steps:

  • Qualified technicians will begin by using a scan tool to access C1758 code stored in the ECU.
  • Technicians will note C1758 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 fluid pressure sensor provides the PCM with the data necessary to monitor the transmission performance. If the fluid pressure increases, the electrical voltage reading from the pressure sensor will increase; if the pressure decreases, the voltage decreases.

This process helps the mechanic narrow down the exact cause of the issue. If the transmission fluid fix did not cause the code to disappear from the PCM, then next step is to inspect the electrical components, and to continue working through possible repairs until the correct issue is found.

Sometimes C1758 code comes with C175800 code.

Diagnosis Of Engine Error OBD Code C1758

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a C1758 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.

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.
