P2432 Scion Code - Secondary Air Injection System Air Flow/Pressure Sensor Circuit Low Bank 1
Quick Answer
The Secondary Air injection (AIR) system consists of an air pump, the Air Switching Valve (ASV), a pressure sensor, the Air Injection Control Driver (AID) and the Engine Control Module (ECM). Common causes include Faulty Pressure Sensor, Pressure Sensor harness is open or shorted, Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2432 Scion Description
The AID drives the ASV and the air pump according to command signals transmitted by the ECM. The pressure sensor detects the pressure in the secondary air passage when the AIR system is ON and OFF, and transmits pressure signal to the ECM.
The AID is not only equipped to drive the pump and valve, but also with a diagnosis function to detect malfunctions in the AIR system circuit.
HINT: As a large current is required to drive the air pump and ASV, an AID has been added to the previous system.
What are the Possible Causes of the DTC P2432 Scion?
- Faulty Pressure Sensor
- Pressure Sensor harness is open or shorted
- Pressure Sensor circuit poor electrical connection

What are the common symptoms of code P2432 in a Scion?
Symptoms may include the check engine light turning on, reduced engine performance, rough idling, and possible increased emissions during cold starts.
What causes the P2432 code to appear in a Scion?
Common causes include a faulty air flow/pressure sensor, wiring or connector issues, a malfunctioning secondary air pump, or clogs in the secondary air injection system.
How is the P2432 code diagnosed in a Scion?
A mechanic will check for related codes, visually inspect the wiring and connectors, test the air flow/pressure sensor, and verify the operation of the secondary air pump.
Can a faulty sensor cause the P2432 code?
Yes, a defective secondary air injection air flow/pressure sensor is a primary cause of the P2432 code.
How can I fix the P2432 code on my Scion?
Repairs may include replacing the air flow/pressure sensor, repairing damaged wiring or connectors, cleaning clogged air injection lines, or replacing the secondary air pump if necessary.
Is it safe to drive with a P2432 code on a Scion?
While the vehicle may still be drivable, ignoring the issue can lead to increased emissions, reduced performance, and potential damage to the secondary air injection system.
How much does it cost to fix a P2432 code on a Scion?
Repairs can range from $100 to $500 or more, depending on whether the issue is a simple wiring repair or a more expensive part replacement like the air pump or sensor.
Can a dirty air filter cause the P2432 code?
While unlikely, a severely clogged air filter could potentially restrict airflow and indirectly contribute to secondary air injection system issues.
Does the P2432 code affect emissions testing?
Yes, a P2432 code can cause your vehicle to fail an emissions test due to improper operation of the secondary air injection system.
