P0026 is a code that signals an issue with your Mercury Montego’s intake valve control solenoid circuit. In layman’s terms, the circuit is not complying with the Powertrain Control Module’s commands. It sent a signal to the intake valve control solenoid, and it, for whatever reason, failed. P0026 is a generic code (it has the … Read more
P0152 is a common OBDII code that occurs in many vehicles, including the Mercury Montego. It indicates that the bank 2 sensor 1 O2 sensor is reporting a voltage level that is higher than its normal operating range. P0152 Definition: O2 Sensor – High Voltage – B2S1 O2 Sensor Oxygen sensors are responsible for metering the … Read more
P0501 is an OBD2 trouble code that indicates there is an issue with your Mercury Montego’s Vehicle Speed Sensor (VSS). It occurs when the Powertrain Control Module (PCM) gets a signal from the VSS outside its normal operating range (in terms of voltage). P0501 is a generic powertrain code, which means it has the same … Read more
P0008 is a somewhat uncommon OBD2 trouble code that can occur in the Mercury Montego. It indicates that the crankshaft and camshaft are not synchronized properly, and should be considered a breakdown risk. Driving your Montego with P0008 can lead to engine damage and a costly repair. While P0008 is a generic code (it has … Read more
P144C is a Ford-only DTC trouble code, and as such, it applies to your Mercury Montego. It indicates that the EVAP canister purge check valve is not performing within spec. P144C is most often fixed by replacing the EVAP purge valve assembly (due to the purge valve being stuck open or closed), which can be … Read more
P0725 is a common OBD2 code that can occur in the Mercury Montego. It indicates an issue with the engine speed sensor input circuit (which measures the engine speed at the input shaft and helps the PCM determine when and how hard to shift the transmission). It’s a generic code, which means it has the … Read more
P0193 is a generic OBD-II code that can occur in the Mercury Montego. It indicates that your Montego’s fuel rail pressure sensor is sending a signal to the PCM that is above its normal operating range (in terms of voltage value). While P0193 is a generic code (it has the same meaning for any vehicle … Read more
P0523 is a standard OBD2 trouble code that can occur in the Mercury Montego. In layman’s terms, it indicates the signal from the oil pressure sensor is higher than its normal operating range (in terms of voltage). P0523 is generic (it has the same definition for all vehicles), repair steps will depend on your Montego’s … Read more
P0705 is a very common transmission-related trouble code that can occur in the Mercury Montego. In layman’s terms, it means that your Montego can’t tell what gear you’ve selected, which can have some real consequences on how it drives. It’s most likely caused by a bad Transmission Range Sensor (TRS), but there are other causes … Read more
P1450 is a manufacturer-specific trouble code. In the case of Ford-made vehicles (such as the Mercury Montego), it indicates that the pressure in the fuel tank is not bleeding up to the engine. This code is very common, and not a breakdown risk when it appears by itself. Far and away, the most common cause … Read more
