P0000 is a rare OBD2 fault code that can affect the Hyundai i30. While there are over 10,000 DTC “P” codes, this is the only one reserved for “no fault detected” in your car’s ECU (engine control unit) memory. It tells the scanner accessing the ECU that no codes are …

P0523 is a standard OBD2 trouble code that can occur in the Hyundai i30. In layman’s terms, it indicates the signal from the oil pressure sensor is higher than its normal operating range (in terms of voltage). P0523 is generic (it has the same definition for all vehicles), repair steps …

P0705 is a very common transmission-related trouble code that can occur in the Hyundai i30. In layman’s terms, it means that your i30 can’t tell what gear you’ve selected, which can have some real consequences on how it drives. It’s most likely caused by a bad Transmission Range Sensor (TRS), …

P1326 is a very common code to find in the Hyundai i30. It indicates that the Knock Sensor Detection System has detected excess engine vibration. An actual engine knock most commonly causes it, but a bad knock sensor or wiring problems are also common causes. Repairing P1326 should be considered …

Daytime running lights (or DRL) are specialized lights that come on when your Hyundai i30’s regular headlights are turned off. Their purpose is to make it easier for other drivers to see you, theoretically decreasing the odds of getting into an accident. If your i30’s DRL warning light is on, …

P0605 is a relatively rare OBD-II trouble code that can occur in the Hyundai i30. It indicates that PCM (powertrain control module) is not passing its ROM (read-only memory) self-test when you turn the ignition on. While P0605 is a generic code (it has the same meaning for any car …

P0116 indicates that your Hyundai i30’s engine coolant temperature sensor is sending a signal to the PCM (powertrain control module) that is outside of its normal operating range (in terms of voltage). While P0116 is a generic OBD2 code (it has the same definition for any car or truck), it …

P0117 is a generic OBD2 code.  It indicates that your Hyundai i30’s PCM (powertrain control module) has detected the signal coming from the engine coolant temp (ECT) sensor has a voltage level below its normal operating range. With the ECT sensor, as the voltage level drops, it will appear that …

P0036 is a very common O2 sensor-related trouble code. It’s generic, which means it has the same definition for the Hyundai i30 as any other vehicle. This code is almost always caused by a bad heated oxygen sensor or wiring issue and is almost always symptom-free. P0036 should NOT be …

P0058 is a not too common and OBDII trouble code that occurs in the Hyundai i30. It indicates that the heated oxygen sensor (which we’ll be referring to as HO2S a lot) heater control circuit located at B2S2 is sending a signal to the PCM that is outside of its …
