The automobile fault code p120e can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P120E fault code is related to the Fuel Pressure Sensor Circuit ‘A’ in the Powertrain Control Module (PCM). The PCM constantly monitors this circuit to ensure it is operating within the factory specifications.

When the Fuel Pressure Sensor Circuit ‘A’ deviates excessively from these specifications, the PCM will set the P120E code.

This code indicates a potential issue with the fuel pressure sensor circuit, which may require further investigation and repair.

What are the possible causes for the automobile fault code P120E?

If you see the engine light or service engine soon warning light on, it could be due to the fault code P120E. This code is typically caused by a faulty fuel pressure sensor circuit ‘A’, an open or shorted fuel pressure sensor circuit ‘A’ harness, or a poor electrical connection in the fuel pressure sensor circuit ‘A’. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or broken pins. Make sure to address any damaged components and ensure a secure electrical connection.

How can I visually inspect the wiring harness and connectors to fix the P120E fault code?

To fix the P120E fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the issue lies with the faulty fuel pressure sensor circuit or if there is a poor electrical connection. Take note of any findings during the inspection to determine the next steps for resolving the problem.

What should I look for when checking for damaged components and connector pins to resolve the P120E fault code?

When resolving the P120E fault code, start by checking for damaged components and connector pins. Visually inspect the related wiring harness and connectors, looking for any signs of damage such as broken, bent, pushed out, or corroded connector pins. This can help identify if the cause of the fault code is a faulty fuel pressure sensor circuit or if there is an open or shorted circuit or poor electrical connection. Take the time to thoroughly examine these areas to ensure a proper fix.
