P2433 Scion Code - Secondary Air Injection System Air Flow/Pressure Sensor Circuit High 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 P2433 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 P2433 Scion?
- Faulty Pressure Sensor
- Pressure Sensor harness is open or shorted
- Pressure Sensor circuit poor electrical connection

Frequently Asked Questions about P2433 Scion Code
1. What does code P2433 mean on a Scion?
Code P2433 indicates a problem with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit High Bank 1, meaning the sensor is detecting higher-than-normal voltage levels.
2. What are the common symptoms of code P2433 in a Scion?
Symptoms include the check engine light turning on, reduced engine performance, and possible difficulty passing emissions tests.
3. What causes the P2433 code to appear in a Scion?
Common causes include a faulty air flow/pressure sensor, wiring issues like damaged or corroded connections, or a malfunctioning secondary air injection pump.
4. Can I drive my Scion with the P2433 code active?
While the car may still be drivable, it is not recommended as the issue can impact emissions and potentially cause further damage to the secondary air injection system.
5. How do I diagnose the P2433 code on my Scion?
Use an OBDII scanner to confirm the code, then inspect the air flow/pressure sensor, wiring, and secondary air injection pump for damage or irregularities.
6. How do I fix the P2433 code on a Scion?
Repairs may include replacing the faulty air flow/pressure sensor, repairing or replacing damaged wiring, or replacing the secondary air injection pump.
7. How much does it cost to fix the P2433 code on a Scion?
Repair costs vary, but sensor replacement typically ranges from $100 to $300, while pump replacement can cost $500 or more, depending on labor and parts.
8. Could a dirty air filter cause the P2433 code on a Scion?
No, a dirty air filter is unlikely to cause this code. The issue is related to the air flow/pressure sensor circuit and secondary air injection system.
9. Will clearing the P2433 code solve the problem on my Scion?
Clearing the code may turn off the check engine light temporarily, but the underlying issue must be fixed to prevent the code from returning.
10. Can a faulty ECU cause the P2433 code on a Scion?
While rare, a malfunctioning ECU could potentially misinterpret signals from the air flow/pressure sensor and trigger the code. Inspection of the sensor and wiring should be prioritized first.
