Breeze, Cirrus, Neon & Stratus

1. Remove fuel pump relay from relay Power Distribution Center (PDC). For relay location, check label on underside of PDC cover. Start and run engine until it stalls. Attempt to start engine until it no longer runs. Turn ignition switch to OFF position.
2. Place a rag or towel below quick-connect fitting at fuel rail. Reinstall fuel pump relay into PDC. One or more Diagnostic Trouble Codes (DTCs) may be stored in PCM memory due to fuel pump relay removal. Clear DTCs with scan tool.

Cirrus, Concorde, Intrepid, LHS, Sebring Convertible, Stratus & 300M

1. Remove fuel pump relay from relay Power Distribution Center (PDC). For relay location, check label on underside of PDC cover. Start and run engine until it stalls. Attempt to start engine until it no longer runs. Turn ignition switch to OFF position.
2. Place a rag or towel below quick-connect fitting at fuel rail. Reinstall fuel pump relay into PDC. One or more Diagnostic Trouble Codes (DTCs) may be stored in PCM memory due to fuel pump relay removal. Clear DTCs with scan tool.

Injectors

Disconnect fuel injector to be tested. Using an ohmmeter, measure resistance between injector terminals. Resistance should be 10-16 ohms at 68°F (20°C). If resistance is not as specified, replace fuel injector.

IDLE AIR CONTROL (IAC) MOTOR

See DTC P0505: IDLE AIR CONTROL MOTOR CIRCUITS test in appropriate SELF-DIAGNOSTICS article.

IGNITION SYSTEMS

Note. For basic ignition checks, see BASIC DIAGNOSTIC PROCEDURES - CARS article.

Except 2.5L

Note. Coil-On-Plug (COP) systems are used on 2.7L, 3.2L and 3.5L engines. Each coil fires an individual spark plug.

1. On 2.0L and 2.4L engines, coil No. 1 fires cylinders No. 1 and 4. Coil No. 2 fires cylinders No. 2 and 3. Disconnect coil pack connector. Using an ohmmeter, measure primary resistance between coil pack connector center terminal (battery positive) and each outside terminal (coil negative). See «IGNITION COIL SPECIFICATIONS (EXCEPT 2.5L)»(ref-9127-S15035688302000100600000) table. If primary resistance is not as specified, replace coil pack.
2. Remove spark plug wires from coil. Measure secondary resistance between towers of each individual coil. See «IGNITION COIL SPECIFICATIONS (EXCEPT 2.5L)»(ref-9127-S15035688302000100600000) table. If secondary resistance is not as specified, replace coil pack.

IGNITION COIL SPECIFICATIONS (EXCEPT 2.5L)

2.5L

1. Disconnect distributor 2-pin connector. Using an ohmmeter, measure resistance between terminals. If resistance is .6-.8 ohm, go to next step. If resistance is not .6-.8 ohm, replace ignition coil.
2. Measure resistance between coil tower and each terminal of distributor 2-pin connector. Resistance should be 12,500-18,000 ohms. If resistance is not as specified, replace ignition coil.

Cirrus & Stratus (2.5L)

A resistor is built into distributor cap. Remove distributor cap from engine. Disconnect coil wire. Using a DVOM, measure resistance between distributor cap center button and coil terminal. Resistance should be 5000 ohms. If resistance is not to specification, replace distributor cap. If resistance is to specification, distributor cap is okay.

Evaporative Emission Control System

See DTC P0441: EVAP PURGE FLOW MONITOR FAILURE test in appropriate SELF-DIAGNOSTICS article.

EXHAUST GAS RECIRCULATION (EGR) SYSTEM

Note. For electrical testing of EGR system, see DTC P0401: EGR SYSTEM FAILURE test in appropriate SELF-DIAGNOSTICS article.

EGR System (Breeze, Cirrus & Stratus)

See TEST NTC-3: CHECKING EGR SYSTEM under DIAGNOSTIC TESTS in SELF-DIAGNOSTICS - BREEZE, CIRRUS & STRATUS article.

EGR System (Concorde, Intrepid, LHS & 300M)

See DTC P0401: EGR SYSTEM FAILURE under DIAGNOSTIC TESTS in SELF-DIAGNOSTICS - CONCORDE, INTREPID, LHS & 300M article.

EGR System (Sebring Convertible)

See TEST NTC-3: CHECKING EGR SYSTEM under DIAGNOSTIC TESTS in SELF-DIAGNOSTICS - SEBRING CONVERTIBLE article.

Positive Crankcase Ventilation (PCV) Valve

1. With engine running at curb idle, remove PCV valve from grommet. If valve is functioning properly, a hissing sound will be heard as air passes through valve.
2. With engine running, place finger over valve inlet. Strong vacuum should be felt at valve inlet. Stop engine. Remove and shake PCV valve to ensure a metallic clicking noise can be heard, indicating valve is free. Reinstall PCV valve.
3. Remove crankcase ventilation filter or oil filler cap from valve cover. Hold a piece of stiff paper over opening. After allowing about one minute for crankcase pressure stabilization, paper should be drawn against opening.
4. If paper is held against opening, performance is okay. If paper is not held against opening, replace PCV valve and retest. If performance does not improve, inspect system for restrictions and clean as necessary.
