P0123 Code – Throttle Position Sensor High Input
The P0123 code indicates that the Engine Control Unit (ECU) has detected a high voltage signal from the Throttle Position Sensor (TPS). A high input signal means the ECU interprets…
P0122 Code – Throttle Position Sensor Low Input
The P0122 code indicates that the Engine Control Unit (ECU) has detected a low voltage signal from the Throttle Position Sensor (TPS). A low input signal means the ECU interprets…
P0121 Code – Throttle Position Sensor Range/Performance Problem
The P0121 code indicates that the Engine Control Unit (ECU) has detected that the Throttle Position Sensor (TPS) signal is outside the expected range or not consistent with other sensor…
P0120 Code – Throttle Position Sensor Circuit Malfunction
The P0120 code indicates that the Engine Control Unit (ECU) has detected a malfunction in the Throttle Position Sensor (TPS) circuit. The TPS monitors the position of the throttle valve…
P0118 Code – Engine Coolant Temperature Sensor High Input
The P0119 code indicates that the Engine Control Unit (ECU) has detected an intermittent or unstable signal from the Engine Coolant Temperature (ECT) sensor circuit. Unlike P0117 (low input) or…
BIOS Beep Codes: Complete Guide for PC Hardware Diagnosis
What Are BIOS Beep Codes BIOS beep codes are audio signals generated by the motherboard during the system startup process, specifically during POST (Power-On Self Test). These signals are used…
P0117 Code – Engine Coolant Temperature Sensor Low Input
The P0117 code indicates that the Engine Control Unit (ECU) has detected a low voltage signal from the Engine Coolant Temperature (ECT) sensor. A low input signal usually means the…
P0116 Code – Engine Coolant Temperature Range/Performance
The P0116 code indicates that the Engine Control Unit (ECU) has detected that the Engine Coolant Temperature (ECT) sensor signal is outside the expected range or not changing as it…
P0115 Code – Engine Coolant Temperature Circuit Malfunction
The P0115 code indicates that the Engine Control Unit (ECU) has detected a malfunction in the Engine Coolant Temperature (ECT) sensor circuit. The ECT sensor measures the temperature of the…
P0114 Code – Intake Air Temperature Circuit Intermittent
The P0114 code indicates that the Engine Control Unit (ECU) has detected an intermittent signal from the Intake Air Temperature (IAT) sensor circuit. Unlike P0112 (low input) or P0113 (high…
