P0193 is a generic OBD-II code that can occur in the Toyota Echo. It indicates that your Echo’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 Toyota Echo. 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 Echo’s … Read more
P0705 is a very common transmission-related trouble code that can occur in the Toyota Echo. In layman’s terms, it means that your Echo 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
Daytime running lights (or DRL) are specialized lights that come on when your Toyota Echo’s regular headlights are turned off. Their purpose is to make it easier for other drivers to see you, theoretically decreasing the odds of getting into an accident. If your Echo’s DRL warning light is on, the powertrain control module (commonly … Read more
P2271 is a generic DTC trouble code that can affect the Toyota Echo. It indicates that the oxygen sensor located on bank 1 in the second position is continuously sending voltage with a value that is too rich. There are oxygen sensors on both sides of the catalytic converter. The “upstream” one is used for … Read more
P2279 is a generic OBD-II code. It indicates there is a vacuum leak coming from your Toyota Echo’s air intake system. While P2279 is a generic code (it has the same definition for the Echo as it would any other vehicle made after 1996), repair steps will vary based on model year and engine. The … Read more
P0605 is a relatively rare OBD-II trouble code that can occur in the Toyota Echo. It indicates that PCM (powertrain control module) is not passing its ROM (read-only memory) self-test when you turn the ignition on. While P0605 is a generic code (it has the same meaning for any car or truck), it is most … Read more
P0116 indicates that your Toyota Echo’s engine coolant temperature sensor is sending a signal to the PCM (powertrain control module) that is outside of its normal operating range (in terms of voltage). While P0116 is a generic OBD2 code (it has the same definition for any car or truck), it has the same basic causes … Read more
P0117 is a generic OBD2 code. It indicates that your Toyota Echo’s PCM (powertrain control module) has detected the signal coming from the engine coolant temp (ECT) sensor has a voltage level below its normal operating range. With the ECT sensor, as the voltage level drops, it will appear that your Echo is overheating. While … Read more
P0743 is a generic OBD2 code that can occur in the Toyota Echo. It indicates that your ECU/TCM has found an issue with the torque converter clutch solenoid. It is a generic code (meaning it has the same definition for all cars and trucks). Repair steps are going to vary depending on your Echo’s model … Read more
