What it means

On Chrysler vehicles, P1415 relates to a fault in the secondary air injection (AIR) system, which pumps fresh air into the exhaust after a cold start to help the catalytic converter light off and reduce emissions. The powertrain control module has detected that the system is not behaving as expected, for example through a circuit fault or a lack of expected response from the air pump or its control components. The exact test the module uses depends on the model, engine and year.

Symptoms

Check engine light on
Air pump whining loudly, or no pump noise at all on a cold start
Rough or unstable idle just after a cold start
Failed emissions test
Possible reduced performance or higher fuel use if other related faults are present

Possible causes

Faulty air pump or seized pump motorlikely
Open circuit, corroded or loose wiring or connectors to the air pump, relay or switching solenoidlikely
Blown fuse or failed air pump relaylikely
Faulty air switching or diverter valve, or check valve that is stuck, leaking or blockedpossible
Damaged, blocked or disconnected air hoses or pipes, including water ingress or corrosion in the pump or linespossible
Fault in the powertrain control module or its driver circuitrare

How to diagnose

Read all stored and pending codes and the freeze frame data, noting engine temperature and conditions when the code set, and check for other related codes.
Check the relevant fuses and the air pump relay, as per the model's wiring diagram.
Visually inspect the air pump, hoses, pipes and valves for damage, disconnection, corrosion, water ingress or blockage.
Inspect the wiring and connectors to the pump, relay and solenoid for chafing, corrosion, bent pins or looseness.
With a cold engine, listen for the pump running on start-up, and use a scan tool's bi-directional controls, if supported, to command the pump and valves.
Check for power, earth and control signal at the pump and solenoid connectors using a multimeter, following the manufacturer's procedure for that model.
Test the air switching and check valves for free movement and leaks, as per the workshop manual for the engine fitted.
Check for any applicable software updates or technical bulletins for the model before replacing the control module.

How to fix

Replace the air pump if it is seized, noisy or fails its electrical and flow checks.
Replace the blown fuse or faulty relay, and find out why it failed.
Repair or replace damaged wiring, terminals or connectors in the air pump circuit.
Replace faulty air switching, diverter or check valves, and any cracked, blocked or leaking hoses.
Where a known fault in the control module calibration is confirmed by the manufacturer, update the calibration as per the official procedure.

Can I keep driving?

Low severity

The car can normally be driven while you arrange a repair, as this system only operates briefly after a cold start. Get it checked soon to avoid failing an emissions test and to stop further faults, such as water damage to the pump, developing.
