The OBD-II trouble code P1212 on a 2002 Infiniti Q45 indicates a malfunction in the injector control pressure sensor circuit. This sensor is responsible for monitoring the fuel pressure in the high-pressure fuel system. A fault in this circuit can lead to issues with fuel delivery and engine performance. It is recommended to have the sensor and its circuitry inspected and repaired by a qualified mechanic to ensure proper functioning of the vehicle.
FUEL pressure, or possible egr valve malfunction.
first thing i would look at is fuel filter,probably half plugged, then it would be fuel pump. check it by putting a fuel pressure guage on the fuel rail and monitor pressure,hopefully your car has a fuel rail monitoring port.
A TPM (Tire Pressure Monitoring) malfunction on a 2008 BMW 535xi indicates that there is an issue with the tire pressure monitoring system, which can be due to a faulty sensor, low tire pressure, or a malfunction in the system itself. This warning typically appears on the dashboard, alerting the driver to check tire pressures or inspect the system. It's essential to address this issue promptly, as it can affect vehicle safety and performance. A diagnostic check at a dealership or qualified mechanic can help identify the specific cause.
A malfunction indicator light comes on because a detector elsewhere in the item has noticed a malfunction in whatever it is monitoring.
The P0450 code for a Mitsubishi Mirage indicates an issue with the Evaporative Emission System Pressure Sensor, specifically a malfunction or an abnormal reading. This sensor is typically located near the fuel tank, often integrated with the fuel vapor management system. It plays a crucial role in monitoring fuel vapor pressure within the system to prevent emissions. If this code appears, it may trigger a check engine light and could lead to increased emissions or reduced fuel efficiency.
There is no fuel pressure test port on an 02 focus. The computer controls the fuel pressure on these and as such the factory approved method of monitoring fuel pressure is to watch the PID on your scan tool. They do make one that can be added on though between the fuel line and the fuel rail. A quick google search should yield plenty of results to help find one.
The fuel pump driver module (FPDM) on a 2007 Ford Taurus regulates the voltage supplied to the fuel pump, ensuring optimal fuel delivery based on engine demand. It adjusts the pump's speed to improve efficiency and performance, helping to maintain proper fuel pressure. Additionally, the FPDM plays a role in protecting the fuel pump from potential damage by monitoring its operation and can disable the pump if a malfunction is detected.
A tire pressure monitoring valve cap is designed to monitor the air pressure inside a tire. It helps maintain optimal tire pressure by alerting the driver when the pressure is too low, which can improve fuel efficiency, tire wear, and overall safety.
You don't If all tires are at 36 PSI, and the light is still on there is a malfunction. The system will need checked for codes with a scan tool.

The TPMS (Tire Pressure Monitoring System) light on a 2008 Honda CR-V indicates that one or more of the tires may be under-inflated or that there is a malfunction in the system. When the light is illuminated, it’s important to check the tire pressures and inflate them to the recommended levels. If the light remains on after correcting tire pressures, it may indicate a problem with the TPMS itself, requiring further inspection or service. Regularly monitoring tire pressure can enhance safety and improve fuel efficiency.
