Trouble Code Definition Tables

DIAGNOSTIC CODES - ELANTRA

Trouble Code Fault Item Probable Cause (1) See:
9 (2) (2) -
11 O2 Sensor Fuel Pressure, Injectors, Vacuum Leak, O2 Sensor Figure
12 Airflow Sensor Airflow Sensor Figure
13 Intake Air Temperature Sensor Intake Air Temperature Sensor Figure
14 Throttle Position Sensor Throttle Position Sensor, IdleSwitch Figure
21 Coolant Temperature Sensor Coolant Temperature Sensor Figure
22 Crank Angle Sensor Crank Angle Sensor Figure
23 TDC Sensor (No. 1 Cylinder) Distributor -
24 Vehicle Speed Sensor Reed Switch Vehicle Speed Sensor Reed Switch -
25 Barometric Pressure Sensor Barometric Pressure Sensor Figure
41 Fuel Injector Injector Coil Resistance Figure
42 Fuel Pump Control Relay -
43 EGR Temperature Sensor (Calif. Only) EGR Temp. Sensor, Valve, Control Solenoid, Control Vacuum Figure
44 Ignition Coil Ignition Coil, Power Transistor Figure
(1) Faulty components, harnesses and connectors are always a probable cause for setting a fault code.
(2) Nine short pulses on voltmeter or NORMAL message on MUT indicates no trouble codes in memory. Continuous voltage reading on voltmeter indicates faulty ECU.
