P1229 TOYOTA - Fuel System Over Pressure
- Defective fuel pressure regulator

- Faulty wiring/fuel pump wiring
- Faulty Engine Control Module (ECM)
- Engine Light ON (or Service Engine Soon Warning Light)
P1229 Toyota DescriptionFuel 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. The fuel system on your Toyota is controlled by the fuel pressure regulator and most problems with over fueling will come from this part, or wiring to it. When there is a problem with pressure in the system, a trouble code from the vehicle's Engine Control Module (ECM) is stored; when the problem is too much pressure, the dashboard will illuminate the SES or check engine light to indicate that code P1229 has been stored in your vehicle's ECM.
