P0158 is an OBDII code that occurs in many vehicles, including the Chevy Equinox. The code is triggered when: The voltage at the O2 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
P0157 is a common OBDII code that occurs in the Chevy Equinox, it’s a general code (this means that it has the same meaning for any vehicle). This code typically indicates that there is an issue with the wiring or harness going to the sensor, or the sensor itself is bad. There are other things that … Read more
P0153 is a common OBDII code that occurs in many vehicles, including the Chevy Equinox. The code is triggered when there is an issue with the response time from the O2 sensor when switching voltage levels. The Oxygen sensor is responsible for helping the ECM monitor oxygen levels in the exhaust in order to … Read more
P0139 is a common OBDII code that occurs in many vehicles, including the Chevy Equinox. 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 Chevy Equinox. 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 Chevy Equinox, 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 Chevy Equinox. 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. Chevy Equinox 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 Chevy Equinox’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 (Chevy Equinox 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 Equinox’s computer uses the … Read more
