P0137 is a fairly common OBDII code that occurs in the Buick Rainier, 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 Buick Rainier. 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. Buick Rainier 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 Buick Rainier’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 (Buick Rainier 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 Rainier’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 Buick Rainier 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 Buick Rainier, 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 Rainier, the most common issue is either going to be … Read more
The Buick Rainier 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 Rainier’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code. P0335 Symptoms: Buick Rainier … Read more
P0138 is a common OBDII code that occurs in many vehicles, including theBuick Rainier. 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 theBuick Rainier. 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
