Peugeot 307 ECU Repair

Peugeot 307 ECU Repair

The owner of the Peugeot 307 1.6i called our garage and reported that there was a malfunction in the ECU, the engine light turned on on the indicator screen and the vehicle misfired while idling (Ecu Repair).

We said we would help if he sent the ECU to us. Then we took the vehicle’s ECU to the desktop.

How to repair Peugeot 307 ECU?

We start to examine the BOSCH ME7.4.4 Ecu, which belongs to the Peugeot 307 1.6i vehicle, on the desktop. First of all, we make a connection between BOSCH ME7.4.4 and Ecutest Ecu Simulation and Test Device.

We made this connection with the Universal Socket, which is provided with the Ecutest Ecu Simulation and Test Device, allowing you to easily connect to all heavy vehicle and passenger engine Ecu.

Upon the request of our customers, we can make it in the original socket of each engine Ecu, so you can connect the socket directly to the ECU and make your connection.

After making our connection, we open our simulation of the Ecutest Ecu Simulation and Test Device from the computer. After selecting the vehicle brand and model, we confirm the ECU BOSCH ME7.4.4 and enter our simulation screen.

When we run our simulation screen, we first check the sensor supply voltages by clicking the “Sensors Powers” button on the left side of the screen.

When we look at it, we see that it is unproblematic. Later, when we change the values ​​of the sensors on the right, we see that the Throttle Motor Sensor (Throttle Motor) is out of order and it gives a warning in a red light.

Ecu Test Simulator

After finding the fault, we first see the internal diagram of the BOSCH ME7.4.4 ECU by clicking the “Component Description” button on our simulation screen. Here it is written the role and brand of the circuit elements.

Here we find the circuit element that controls the Throttle Motor Sensor. Then click ‘Electric Diagram’ to see the pin ends and signal types connected to the Throttle Motor sensor. Thus, thanks to the Ecutest Ecu Simulation and Test Device, we learn both the circuit element and the pin ends.

With the help of the multimeter, we first check the circuit element connected to the ECU, we see that the circuit element works without any problems.

When we look at the pins of the ECU, we find that they are not connected to the circuit element and that there is a break in the circuit path. Then we complete this disconnection without damaging the ECU.

Then we connect the BOSCH ME7.4.4 Engine Ecu back to the Ecutest Ecu Simulation and Test Device. When we checked again, we observed that the problem was resolved and the ECU was working without any problems.

Thus, thanks to the Ecutest Ecu Simulation and Testing Device, we can solve the problem of the BOSCH ME7.4.4 ECU in the fastest, easiest and lowest cost. We deliver the BOSCH ME7.4.4 ECU to our customer.
