TIP: This helpful resource site will reveal problem, cause, solution for every obd fault code which is picked up via computer software for car diagnostics You can also access the database by downloading the printable offline version of OBD2 codes ( ideal for auto mechanics). This page lists 5,000+ generic and manufacturer OBD2 Diagnostic Trouble Codes. So to avoid unpredictable hazards when fixing a vehicle based on it's DTC codes - make sure you get a reliable OBD2 reader that'll thoroughly scan the vehicle for faults beyond traditional DTC OBD2 codes. As a result, oxygen sensors are likely to report fuel mixture problems. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.ĭTCs may also be triggered by faults earlier down the line.

The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.įor example, if a DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. Parts or components should not be replaced with reference to only a malfunctioning indicator lamp (check engine fault light). Is it safe to reset an OBD2 Diagnostic Trouble Code? They're the cause for indicator light malfunction on the dashboard.Ĭodes should be used in conjunction with the vehicle's service manual to discover which systems, circuits or components should be tested to fully diagnose the fault with a car code reader or professional OBD2 software. These DTC's identify a particular problem area and are intended to provide the technician with a guide as to where a fault might be occurring within the vehicle. These OBD2 codes are stored when a sensor in the car reports a reading that is outside the normal/accepted range (Eg: fuel mixture too rich). These are stored in response to a problem found in the car by the system. Diagnostic trouble codes (or fault codes) are obd2 codes that are stored by the on-board computer diagnostic system.
