Causes
- Failed or seized AIR pump (electric)
- Blocked, collapsed or disconnected AIR hoses/piping
- Failed one-way/check valve or diverter/solenoid valve
- Blown fuse, bad relay, or poor power/ground to pump or solenoid
- Wiring harness damage, corrosion, or poor connector contact
- Stuck open/closed control valve or vacuum actuator (if equipped)
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Failed emissions test or higher cold-start tailpipe emissions
- Audible abnormal/no AIR pump noise (no noise when commanded or grinding)
- Rough idle or stumble on cold start (occasionally)
- Unusual exhaust odors or visible exhaust changes during warm-up
What to check
- Verify stored freeze frame data and all related DTCs with a scan tool
- Listen for AIR pump operation during cold start or commanded test
- Inspect AIR pump electrical connector, fuse(s), and relay(s)
- Visually inspect hoses, check valve and diverter valve for leaks or damage
- Attempt to command AIR pump/valve ON with a scan tool and observe operation
- Check for air flow at exhaust ports (careful — hot components)
Signal parameters
- AIR pump supply voltage: approx. battery voltage (11–14.5 V) when relay/power applied
- AIR pump current draw: typically several amps under normal load (varies by model; expect low single digits to teens of amps) — abnormally high or zero indicates fault
- Control solenoid/valve command: switched 12 V or ground drive from ECM (ON/OFF duty visible with scan tool or DVOM)
- ECM AIR status: commanded ON/OFF and runtime duration available via scan tool
- Diagnostic trouble criteria: ECM expects pump run or valve position within defined time after cold start
Diagnostic algorithm
- Retrieve and record all codes and freeze frame data. Note related codes (oxygen sensors, catalyst).
- With a scan tool, attempt to actuate the AIR pump and diverter/solenoid while observing status and any live data. Listen for pump and feel for air flow at fittings (use gloves; components may be hot).
- Inspect fuses and relays for the AIR pump circuit; test/replace relay and check for voltage at pump power pin with relay energized.
- Inspect wiring and connectors for damage, corrosion, or poor ground. Wiggle-test connectors while commanding system to check for intermittent faults.
- Apply battery voltage directly to the AIR pump (bench or in-vehicle with precautions) to verify mechanical operation; measure current draw and compare to expected range.
- Check one-way/check valve and diverter valve operation (vacuum or electrical actuation as applicable). Confirm air flow direction and that valves open/close properly.
- Perform a smoke test or pressurize AIR plumbing to locate leaks, collapsed hoses, or blockages. Replace cracked or collapsed hoses and defective valves.
- If wiring, pump, and valves test good, inspect exhaust side (manifold, catalytic converter) for restrictions that could prevent flow and trigger the code.
- Repair/replace failed components (pump, valve, hoses, relay, fuse, wiring) as indicated. Clear codes and run drive cycle to verify repair.
- If system electrical tests are inconclusive, consult Chrysler service information for component-specific test values and ECM diagnostic procedures; consider ECM fault only after isolating wiring and components.
Likely causes
- AIR pump does not run when commanded (electrical fault or pump failure)
- AIR pump runs but no air flow to exhaust due to blocked/disconnected hose or check valve
- Control solenoid/diverter valve not actuating due to bad valve or wiring
- Fuse/relay failure preventing pump operation
- Intermittent wiring/connector fault causing false error
- Mechanical restriction in plumbing or failed one-way valve
Fault status
Status
Malfunction Indicator Lamp (MIL) on due to Secondary Air Injection system fault. Emissions control performance may be reduced.
