Venza Fuel Pressure Sensor Issue

My 2022 Toyota Venza Hybrid with 106358 km has the check engine light on, rough engine running, stalls at idle, and jerking during acceleration. Diagnostics suggest a defective fuel pressure sensor. Could a defective cable or plug connection to the fuel pressure sensor cause these symptoms?

Summary of the thread

A 2022 Toyota Venza Hybrid exhibited issues such as a check engine light, rough engine running, stalling at idle, and jerking during acceleration. Diagnostics indicated a defective fuel pressure sensor, but the problem was traced to a faulty cable connection to the sensor. Repair involved replacing the cable and recalibrating the sensor, resolving the performance issues.

Interesting. I drive a Venza too. I had similar symptoms a while back. Did you happen to check the fuel injectors themselves? Sometimes a misfire due to a faulty injector can trigger similar fault codes and engine behavior. Is the roughness consistent, or does it come and go?

I haven't inspected the fuel injectors directly. But considering the error code implicates the fuel pressure sensor, could a malfunctioning injector convincingly mimic such a failure, presenting identical symptoms? Should I examine the injectors before replacing the sensor?

While the code points to the sensor, these systems are interconnected. A bad injector can definitely mess with the fuel pressure readings. Given the symptoms and the mileage, it might be worth having a workshop take a look. They can perform more thorough diagnostics.

Following your recommendation, I sought professional diagnosis at a reputable workshop. The issue stemmed from a defective cable connection to the fuel pressure sensor, resulting in erratic fuel pressure readings. The repair, consisting of cable replacement and sensor recalibration, amounted to 95€. The vehicle now performs optimally.
