P2433 DODGE code

The P2433 diagnostic trouble code is an indication that there is a problem with the airflow/pressure sensor circuitry of the secondary air injection system. The secondary air injection system allows fresh air into the exhaust system.

What is a P2433 code?

OBD-II Code P2433 is defined as a Secondary Air Injection System Air Flow/Pressure Sensor Circuit. The Secondary Air Injection System (AIR) pumps outside fresh air into the Exhaust System during cold engine start up.

What is a secondary air injection 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 PCM supplies 5 volts to power the sensor and another 5 volts as a reference or signal while finally supplying the much needed ground on the third circuit.

How do I fix error code P2431?

What repairs can fix the P2431 code?

  1. Replacing the secondary air pump.
  2. Repairing or replacing a wiring harness.
  3. Resolving poor electrical connections.

What is code P0418 mean?

OBD-II Code P0418 is defined as a Secondary Air Injection System Control “A” Circuit. The Secondary Air Injection System pumps outside fresh air into the Exhaust System during cold engine start up. This additional air helps burn up the highly rich exhaust emissions that are produced when the engine is warming up.

How do you fix a secondary air injection system malfunction?

What repairs can fix the P0410 code?

  1. Replacing the air injection pump and power relay.
  2. Replacing O2 sensors that respond too slow as they age.
  3. Replacing the air injection pump intake filter clogged with debris.

Can you drive without secondary air pump?

Technically speaking, you can drive without a secondary injection pump. However, doing so is not advised. This stems from the fact that a faulty secondary injection pump can cause a host of drivability-related issues, most of which can vary significantly in severity, on a case-by-case basis.

Where is the secondary air injection system located?

The secondary air injection pump is usually located on the engine or at least in the engine bay. It can sometimes be hidden deep into the engine bay, but mostly you will find it installed pretty visible on the engine.

What does the secondary air system do?

What Does a Secondary Air Pump Do? The secondary air injection pump (also referred to as a smog pump or SAI pump) is responsible for lowering the number of carbon emissions that come out of the tailpipe of a vehicle. This is necessary since a vehicle engine is never 100% efficient in the combustion process.

How does a secondary air injection system work?

Secondary air injection systems pump outside air into the exhaust stream so unburned fuel can be burned. Early air systems have a belt-driven air pump. Newer aspirated air systems use the vacuum created by an exhaust pulse to pull air into the pipe. The latest systems use an electric motor to pump air.
