P0402 is an OBDII trouble code that’ll pop up in the Acura RLX. 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 … Read more
P0139 is a common OBDII code that occurs in many vehicles, including the Acura RLX. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The Oxygen sensors are responsible for helping the ECM meter oxygen levels in the exhaust, and helping to … Read more
P0140 is a generic OBDII trouble code. It has the same meaning for any vehicle with OBDII, including the Acura RLX. It means that the PCM/ECM is not detecting any activity from the sensor. It doesn’t mean that the O2 sensor isn’t getting power, but that the voltage isn’t changing, which is the “no activity”. … Read more
P0137 is a fairly common OBDII code that occurs in the Acura RLX, it’s a general code. This means that it has the same meaning for any vehicle. This code is supposed to let you know that there is an issue with the wiring or harness going to the sensor, or the sensor itself is … Read more
P0136 is a common OBDII code that occurs in the Acura RLX. 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. Acura RLX 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 Acura RLX’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 (Acura RLX 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 RLX’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 Acura RLX 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
With the Acura RLX, 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 RLX, the most common issue is either going to be … Read more
