- Repair damaged wiring to the fuel tank pressure sensor.
What can cause a P0452 code?
Error Code P0452 is defined as Evaporative Emission Control System Pressure Sensor Low Input. This means there’s an ongoing problem in the fuel tank pressure sensor or evaporative pressure sensor, usually caused by a vacuum leak or loose fuel gap.
How do I know if my fuel tank pressure sensor is bad?
Signs of a bad fuel tank pressure sensor
- Your check engine warning light comes on.
- Your fuel consumption increases noticeably.
- A loss of power and acceleration.
- Hard starting.
- Stalling.
- Black smoke coming out of tailpipe.

What tells the fuel pump on?
Fuel pump turns on When you first turn the key on your car, the PCM immediately powers the fuel pump to pressurize the fuel system. When the motor is cranking, and the key is in the crank position, the PCM will supply power to the fuel pump until the ignition key is no longer in the cranking position.
Is ECM the same as PCM?
The terms PCM (Powertrain Control Module), ECU (Engine Control Unit) and ECM (Engine Control Module) can sometimes be used as interchangeable generic phrases for the same thing – a control unit for the engine/transmission system.
What all does the ECM control?
The ECM, or electronic control module, is the computer responsible for controlling all of the engine management functions. It is the central control unit of most vehicles and controls a variety of functions, such as electrical system power distribution, emissions, ignition, and fuel systems.
Can ECM affect transmission?
The ECM controls a number of systems, but the most important ones for our purposes are the air to fuel ratio, the engine timing. It also controls the transmission in automatic transmission vehicles, and valve timing on vehicles with variable valve timing.
How much does an ECM cost?
The cost for the new ECM will typically be around $800, with labor around $100, bringing the average total expense for an ECM replacement to approximately $900 before taxes and fees. This can increase depending on the shop you go to or the type of car you, running as high as $2,000.
