P2424 Code - HC Adsorption Catalyst Efficiency Below Threshold Bank 2
Quick Answer
The Engine Control Module (ECM) monitors the phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal. Common causes include HC adsorption catalyst (under floor), Exhaust tube, Intake air leaks. 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.
- What it means
- P2424 indicates HC Adsorption Catalyst Efficiency Below Threshold Bank 2.
- Common causes
- Common causes include HC adsorption catalyst (under floor), Exhaust tube, Intake air leaks.
- Severity
- High - diagnose this code as soon as possible.
- Can I drive?
- Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
Code P2424 Description
The phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal becomes small as the HC adsorption catalyst (under floor) is deteriorated.
When the phase gap between heated oxygen sensor 2 signal and heated oxygen sensor 3 signal approaches a specified limit value, the HC adsorption catalyst (under floor) malfunction is diagnosed.
What are the Possible Causes of the DTC P2424?
- HC adsorption catalyst (under floor)
- Exhaust tube
- Intake air leaks
- Faulty Fuel injector
- Fuel injector leaks
- Faulty Spark plug
- Improper ignition timing
How to Fix the DTC P2424?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2424 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
