The P1229 diagnostic trouble code indicates a sensor power supply circuit shorted. This means that there is a problem with the power supply to a sensor in the vehicle, causing a short circuit.

2019年7月20日 · Code P1229 Toyota Description. Fuel must come through lines at an ideal pressure to keep your engine running properly. A fault in the system can cause for the system to over fuel and increase pressure beyond the ideal range.

OBD-II code P1229 represents a problem with the pressure of your Toyota's fuel system. Shop OEM fuel pumps here. Fuel must come through lines at an ideal pressure to keep your engine running properly. A fault in the system can cause the system to over fuel and increase pressure beyond the ideal range.

2019年7月20日 · What are the possible causes of OBDII code P1229 Toyota (Fuel System Over Pressure)? - The code can be triggered by a faulty fuel pressure regulator, a clogged fuel filter, a malfunctioning fuel pump, or issues with the fuel pressure sensor.

To resolve fault code P1229, start by checking the harness body ground and inspecting the Accelerator Pedal Position (APP) sensor, Power Steering Pressure (PSP) sensor, Refrigerant Pressure sensor, and EVAP Control System Pressure sensor.

2022年11月5日 · How to Fix the DTC P1229? Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins …

Engine started, system voltage over 10.0v, and the PCM detected an unexpected high or low voltage condition on the Accelerator Pedal Position (APP) Sensor 2 power source (VREF) circuit. The APP2 sensor is installed on the upper end of the throttle unit.

2021年5月25日 · P1229 TOYOTA Meaning. Fuel must flow through the lines at the ideal pressure for your engine to run properly. A fault in the system can cause the system to overload and increase the pressure beyond the ideal range. Your Toyota's fuel system is controlled by the fuel pressure regulator and most boost issues will come from this part or its wiring.

The P1229 OBDII fault code is set when the ECM (Engine Control Module) detects that the actual fuel pressure has exceeded its maximum allowable level.
