P0142 Code – O2 Sensor Circuit Malfunction
The P0142 OBD2 code indicates a malfunction in the oxygen sensor circuit for Bank 1 Sensor 3. This sensor is typically located further downstream in the exhaust system, after the…
P0141 Code – O2 Sensor Heater Circuit Malfunction
The P0141 OBD2 code indicates a malfunction in the heater circuit of the oxygen sensor (O2 sensor) located on Bank 1 Sensor 2. This is the downstream oxygen sensor, positioned…
P0140 Code – O2 Sensor Circuit No Activity Detected
The P0140 code indicates that the oxygen sensor (O2 sensor) located on Bank 1 Sensor 2 is showing no activity. This sensor is positioned after the catalytic converter (downstream sensor)…
P0124 Code – Throttle Position Sensor Circuit Intermittent
The P0124 code indicates that the Engine Control Unit (ECU) has detected an intermittent or unstable signal from the Throttle Position Sensor (TPS) circuit. Unlike P0122 (low input) or P0123…
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…
