If your Opel Karl has a humming noise at high speed, it can be distracting and, depending on the cause, dangerous. We’ve outlined the most common reasons why a humming noise in your car gets louder with speed. We’ve also provided an audio sample of each issue to help determine …

P0088 is a common OBD2 trouble code that can occur in the Opel Karl. In layman’s terms, it indicates that your car’s fuel pressure is too high. While P0088 is a generic code, repair steps will vary depending on your Karl’s model year, engine type, and how it regulates fuel …

P0725 is a common OBD2 code that can occur in the Opel Karl. It indicates an issue with the engine speed sensor input circuit (which measures the engine speed at the input shaft and helps the PCM determine when and how hard to shift the transmission). It’s a generic code, …

P0193 is a generic OBD-II code that can occur in the Opel Karl. It indicates that your Karl’s fuel rail pressure sensor is sending a signal to the PCM that is above its normal operating range (in terms of voltage value). While P0193 is a generic code (it has the …

P0523 is a standard OBD2 trouble code that can occur in the Opel Karl. 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 Opel Karl. In layman’s terms, it means that your Karl 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), …

P015D is a generic trouble code, which means that it has the same definition for the Opel Karl as it would any other vehicle. The code indicates that the Oxygen (O2) sensor on bank 2 is not cycling from lean to rich as fast as it should be. P015D is …

P0116 indicates that your Opel Karl’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 Opel Karl’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 Opel Karl 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 …
