-
Oxygen sensor circuit malfunction — Bank 1 Sensor 1
The upstream oxygen sensor circuit has a fault.
-
Oxygen sensor circuit low voltage — Bank 1 Sensor 1
The upstream oxygen sensor voltage is stuck low, indicating a very lean signal or sensor fault.
-
O2 sensor slow response — Bank 1 Sensor 1
The upstream oxygen sensor responds too slowly.
-
Oxygen sensor no activity detected — Bank 1 Sensor 1
The upstream oxygen sensor never changes voltage — no signal activity.
-
Oxygen sensor heater circuit malfunction — Bank 1 Sensor 1
The O2 sensor heater is not working, slowing warm-up and risking emissions failure.
-
O2 sensor circuit malfunction — Bank 1 Sensor 2
The downstream oxygen sensor circuit has a fault.
-
O2 sensor circuit low voltage — Bank 1 Sensor 2
The downstream O2 sensor voltage is too low.
-
Oxygen sensor heater circuit malfunction — Bank 1 Sensor 2
The downstream O2 sensor heater circuit has a fault.
-
Oxygen sensor circuit malfunction — Bank 2 Sensor 1
The bank 2 upstream oxygen sensor circuit has a fault.
-
O2 sensor heater circuit — Bank 2 Sensor 2
The bank 2 downstream O2 sensor heater has a fault.
-
System too lean — Bank 1
The engine runs with too much air or too little fuel on bank 1. Fuel trims add fuel to compensate.
-
System too rich — Bank 1
The engine runs with too much fuel or too little air on bank 1.
-
System too lean — Bank 2
Bank 2 is running lean — fuel trims are adding fuel.
-
Fuel rail pressure sensor range / performance
The rail pressure sensor reading is not plausible.
-
Injector circuit malfunction — Cylinder 1
The fuel injector on cylinder 1 has an electrical fault.
-
Injector circuit malfunction — Cylinder 2
The fuel injector on cylinder 2 has an electrical fault.
-
Injector circuit malfunction — Cylinder 3
The fuel injector on cylinder 3 has an electrical fault.
-
Injector circuit malfunction — Cylinder 4
The fuel injector on cylinder 4 has an electrical fault.
-
Engine coolant over temperature condition
The engine exceeded the maximum coolant temperature — stop driving.
-
Throttle position sensor B circuit malfunction
The second throttle position sensor circuit has a fault.
-
Throttle position sensor B range / performance
The second throttle position track is out of range.
-
Fuel pump primary circuit malfunction
The fuel pump control circuit has an electrical fault.
-
Turbocharger overboost condition
Boost pressure exceeded the maximum allowed limit and was cut.
-
Injector 1 circuit low
The cylinder 1 injector circuit reads too low.
