P0601 Internal Control Module Memory Checksum Error Fault: What is it?

P0601 Internal Control Module Memory Checksum Error Fault: What is it?

Diagnostic trouble code P0601 is a ‘Memory Check Sum Error in the Internal Control Module’. The code is generated when the PCM (powertrain control module) detects a problem internally, usually a failed memory test sum. Verification is a mathematical procedure ...

P0506 Engine’s Idle Speed is Lower Than the Expected Fault: What is it?

P0506 Engine’s Idle Speed is Lower Than the Expected Fault: What is it?

This system is a vital component in your car. This system keeps your engine from stalling, even when you turn on power-consuming devices like the air conditioner. The Powertrain Control Module (PCM), when the idle control system revolutions per minutes ...

P0123 Throttle/Pedal Position Sensor/Switch A Circuit High Fault: What is it ?

P0123 Throttle/Pedal Position Sensor/Switch A Circuit High Fault: What is it ?

The throttle position sensor (TPS), is an electronic component that helps the engine computer determine the optimal ignition timing and fuel injector. This is done by measuring how open the throttle valve actually is. As a failsafe measure, vehicles with ...

P0107 Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage Fault: What is it?

P0107 Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage Fault: What is it?

This pressure can be affected by engine speed, throttle opening, air temperature and barometric pressure (BARO). This pressure is affected by the engine speed, throttle position, air temperature and barometric pressure. The Powertrain Control Module uses the MAP signals for ...

P0030 Oxygen (Lambda) Sensor Heating Circuit (Bank 1 Sensor 1) Malfunction / Open Circuit Fault: What is it?

P0030 Oxygen (Lambda) Sensor Heating Circuit (Bank 1 Sensor 1) Malfunction / Open Circuit Fault: What is it?

Your engine could have up to two oxygen sensors, depending on the make and model of your vehicle. Oxygen sensor are essential components of a vehicle’s emissions system. These sensors measure the amount of oxygen in exhaust gases. These sensors ...

P0193 Fuel Rail Pressure Sensor “A” Circuit High Fault: What is it?

P0193 Fuel Rail Pressure Sensor “A” Circuit High Fault: What is it?

Fuel pressure is one of the key factors that affect engine performance. Fuel pressure is monitored by the fuel pressure sensor. The voltage signal is used to transmit this information to the powertrain controller module (PCM/ECM). This data is used ...
