How do I fix code P2433?

What repairs can fix the P2433 code?

1. Replacing faulty air injection valve.
2. Replacing faulty one-way check valve.
3. Replacing faulty air injection pump.
4. Replacing faulty pressure sensor.
5. Repairing or replacing frayed, broken, or shorted pressure sensor wiring.
6. Repairing or replacing damaged or corroded pressure sensor connector.

Where is secondary air injection valve?

Secondary air valves are an integral part of the secondary air system. They are fitted between the secondary air pump (1) and exhaust manifold. They prevent pressure peaks in the exhaust flow from damaging the secondary air system and exhaust gas or condensate from entering the secondary air pump.

What is a secondary air pressure sensor?

A secondary air injection pressure sensor is used by the Powertrain Control Module or PCM to monitor the air flow from the air injection pump. The sensor returns a certain amount of the reference voltage based upon the amount of pressure changes within the exhaust system.

What does the secondary air injection system do?

Secondary air injection (commonly known as air injection) is a vehicle emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream to allow for a fuller secondary combustion of exhaust gases.

How do you know if you have a bad air pump?

One of the first symptoms of a bad or failing smog pump is a rough running engine. When a smog pump fails the finely tuned air-fuel ratios can be upset, and it will negatively affect the performance of the engine. The engine may have trouble idling, and may drop in engine speed, or stall when the pedal is pressed.

What would be the concern if the SAI one way check valve was stuck open?

If a P2442 code comes up, a one-way check valve is stuck open in the secondary air injection system, causing too much airflow into the exhaust and allowing hot exhaust gas to travel back into the pump. If the PCM receives a voltage reading of more than 10% of the allowed amount the P2442 code will be stored.

What happens when a check valve goes bad?

A common cause is a failed check valve. The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. If the valve fails, water streams back down the well, and the pressure switch turns the pump on again.
