P0740 is one of the most common transmission trouble codes. It means that the Terrain‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. P0740: Torque Converter Clutch Circuit Malfunction The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission … Read more
P0160 is a standard OBDII trouble code. It has the same meaning for any vehicle with OBDII, including the GMC Terrain. When a vehicle has P0160, 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 … Read more
P0118 is a common OBDII trouble code. It is a general code, which means that it’s going to have the same meaning for the GMC Terrain as it would any other vehicle. P0118: Engine Coolant Temp Sensor Circuit → High Input This code is thrown when the resistance coming from the coolant temp sensor … Read more
P0410 is a generic OBDII trouble code. This means that it has the same meaning for the GMC Terrain as it would any other vehicle. It is letting you know that there is an issue with the secondary air injection system. P0410: Secondary Air Injection System → Malfunction The secondary air injection system injects air … Read more
P0506 is a common OBDII trouble code. It is typically triggered when the engine idle speed is lower than the predetermined limit set by the manufacturer. It is a generic code, which means that it has the same meaning for the GMC Terrain as it would any other vehicle. P0506 Symptoms: Terrain Most … Read more
P0156 is an OBDII trouble code that occurs in the GMC Terrain. It is typically caused when the O2 Sensor voltage is not within its specified operating range. Bank two will be the side of the engine with cylinder 2 in the firing order. Sensor 2 is aft of the catalytic converter. … Read more
P0505 is an OBDII code that deals with the idle air control system in the GMC Terrain. It’s a generic code, which means that it has the same meaning for the Terrain as it would any other vehicle (Terrain or not). P0505: Idle Air Control System: Malfunction When P0505 is triggered, it is typically caused … Read more
P0158 is an OBDII code that occurs in many vehicles, including the GMC Terrain. 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 GMC Terrain, 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 GMC Terrain. 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
