The P0151 code is an OBD-II diagnostic trouble code that indicates low voltage in the Volkswagen Beetle’s Oxygen (O2) sensor circuit located at Bank 2, Sensor 1 (B2S1). The B2S1 O2 sensor plays a crucial role in maintaining optimal engine performance by detecting the air-fuel ratio in the exhaust, then sending this data to the … Read more
P0154 is a relatively common trouble code. It’s generic, which means that it has the same meaning for any vehicle with OBDII (Volkswagen Beetle or not). It means that the PCM/ECM is not detecting any activity from the sensor. There can be many reasons for this code to throw. These include a bad o2 … Read more
P0134 is a relatively common OBDII trouble code. It’s generic, which means that it has the same meaning for any vehicle with OBDII. It means that the PCM/ECM is not detecting any activity from the sensor. P0134 Definition P0134: O2 Sensor → No Activity Detected →Bank 1 Sensor 1 The Beetle’s computer uses the … Read more
P0403 is a very common trouble code. It is a generic code, which means that it has the same meaning for the Volkswagen Beetle as it would any other vehicle. It affects the EGR (Exhaust Gas Recirculation System and technically means: P0403: EGR→ Circuit Malfunction A circuit malfunction implies that there is a wiring problem … Read more
P0150 is a very common OBDII code that occurs in the Volkswagen Beetle. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. Volkswagen Beetle P0150 Symptoms Typically, the only symptom of P0150 is going to be the service engine soon light. In some cases, there can be other symptoms … Read more
P0402 is an OBDII trouble code that’ll pop up in the Volkswagen Beetle. It has to do with the emissions system and stands for: P0402: EGR → Excessive Flow Diagnosis The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. The amount of gas cycled … Read more
With the Volkswagen Beetle, P0404 is going to have the same meaning as it would in any other vehicle. It’s a generic powertrain code that stands for: P0404: EGR Circuit → Range/Performance While there are several issues that can throw the P0404 code in the Beetle, the most common issue is either going to be … Read more
The Volkswagen Beetle utilizes a crankshaft position sensor in order to regulate the engine timing. This sensor uses a reluctor to gauge the position of the crank. When the Beetle’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code. P0335 Symptoms: Volkswagen Beetle … Read more
P0138 is a common OBDII code that occurs in many vehicles, including theVolkswagen Beetle. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself There are also some less likely problems … Read more
P0133 is a common OBDII code that occurs in many vehicles, including theVolkswagen Beetle. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The O2 sensor is responsible for helping the ECM meter oxygen levels in the exhaust in order to … Read more
