P2430 Pontiac Code - Secondary Air Injection System Air Flow/Pressure Sensor Circuit Bank 1
Quick Answer
The Secondary Air Injection (AIR) System aids in the reduction of hydrocarbon exhaust emissions during a cold start-up. Common causes include Faulty AIR Pressure Sensor, AIR Pressure Sensor harness is open or shorted, AIR 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 P2430 Pontiac Description
The Powertrain Control Module (PCM) activates the AIR system by simultaneously supplying grounds to the AIR pump and the AIR valve relays. This action closes the relays' internal contacts. The AIR pump and the AIR control solenoid valve/pressure sensor assembly are in turn energized, the pump runs and the control/shut-off valve opens.
The AIR pump sends pressurized fresh air into the pipes/hoses through the open control/shut-off valve, and into the exhaust manifold. The extra air accelerates the catalyst operation, helping it to reach operating temperature faster. The AIR pump remains ON for a short period of time after the control/shut-off valve is commanded OFF. When the AIR pump is commanded OFF it will not run or be activated until the next vehicle start. When the AIR system is inactive, the closed AIR control/shut-off valve prevents air/exhaust flow in either direction.
The AIR system pressure sensor is used to monitor pressure at the AIR control solenoid valve/pressure sensor assembly inlet during the commanded ON/OFF states.
What are the Possible Causes of the DTC P2430 Pontiac?
- Faulty AIR Pressure Sensor
- AIR Pressure Sensor harness is open or shorted
- AIR Pressure Sensor circuit poor electrical connection

Frequently Asked Questions about P2430 Pontiac Code
1. What does the OBDII code P2430 mean for a Pontiac?
P2430 indicates an issue with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit in Bank 1, which helps monitor and control the air injection system.
2. What are the common symptoms of P2430?
Symptoms may include an illuminated check engine light, poor acceleration, reduced fuel efficiency, and increased tailpipe emissions.
3. What causes the P2430 code to appear?
Common causes include a faulty air flow/pressure sensor, damaged wiring or connectors, a malfunctioning secondary air injection pump, or a clogged air injection system.
4. How do I diagnose the P2430 code?
Diagnosis involves checking the air flow/pressure sensor, inspecting wiring and connectors for damage, testing the secondary air injection pump, and scanning the vehicle with an OBDII scanner.
5. Can I drive my Pontiac with a P2430 code?
While the vehicle may still run, driving with a P2430 code can lead to reduced performance and emissions system issues, so it’s best to address it promptly.
6. How do I fix the P2430 code?
Repairs may include replacing the air flow/pressure sensor, repairing damaged wiring, cleaning clogged air passages, or replacing the secondary air injection pump.
7. How much does it cost to fix a P2430 code on a Pontiac?
Repair costs vary, but replacing the air flow/pressure sensor typically costs $100–$300, while more extensive repairs like pump replacement may cost $400–$700.
8. What tools are needed to troubleshoot P2430?
Tools may include an OBDII scanner, multimeter, vacuum gauge, and basic hand tools for inspecting and testing components.
9. Can a clogged secondary air injection system cause P2430?
Yes, a clogged system can restrict airflow and trigger the P2430 code by affecting the sensor readings.
10. Does a faulty secondary air injection pump always trigger P2430?
Not always. A faulty pump can contribute to the issue, but the code specifically refers to a problem with the air flow/pressure sensor circuit.
