Inthis video I go over how I troubleshooted my check engine code 7 "open or short circuit in throttle position sensor" and resolved the issue on my Arctic C Yourcar's TPS 'A' Circuit, like the TPS' B' Circuit, has an anticipated output voltage range (if so equipped). When code P0121 appears, it hints that the Engine Control Module (ECM) has detected that the predicted output voltage of the TPS 'A' circuit has gone above or below the sensor's expected range. When the code activates Backfiring If the engine doesn't have enough air, the air-to-fuel mixture ratio is off, and some fuel might be left after the spark. This fuel then makes its way through the system and could Thethrottle position sensor (TPS) on your 3.3L equipped Nissan Pathfinder (Frontier, Xterra or QX4) is located on the side of the throttle body. As you can see in photo 2 of 2 (in the image viewer) the TP sensor has 2 connectors for a total of 6 wires coming out of both. This is due to the fact that the throttle position sensor is two sensors TheIntake Air Temperature Sensor measures the temperature of the air while it enters the intake of the engine. It's used to control the air/fuel mixture of the engine. It's also part of the pressure control system for the transmission. As temperature changes, so do the sensor's electrical resistance and voltage signal. Vay Tiền Nhanh Chỉ Cần Cmnd Nợ Xấu.

how do you know when your tps sensor is bad
