P0136 is a common OBDII code that occurs in the Hyundai Altos. It is typically caused when the O2 Sensor voltage is not within normal operating range. Bank one will be the side of the engine with cylinder 1 in the firing order. Hyundai Altos P0136 Symptoms Often, the only symptom of P0136 … Read more
The P0151 code is an OBD-II diagnostic trouble code that indicates low voltage in the Hyundai Altos’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 (Hyundai Altos 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 Altos’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 Hyundai Altos 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 Hyundai Altos. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. Hyundai Altos 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 Hyundai Altos. 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 Hyundai Altos, 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 Altos, the most common issue is either going to be … Read more
The Hyundai Altos 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 Altos’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code. P0335 Symptoms: Hyundai Altos … Read more
P0138 is a common OBDII code that occurs in many vehicles, including theHyundai Altos. 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
