Nissan Versa TPMS Light On – Tire Pressures at Specification
The dreaded TPMS light. This tech tip explains a simple diagnostic suggestion.
What Does TPMS Do?
TPMS stands for Tire Pressure Monitoring System. It is an electronic system that keeps an eye on your tire pressure and warns you when a tire is under-inflated.
Oxygen Sensor Voltage Codes – Part 2
In Part 1, we began to discuss the importance of oxygen sensor voltage codes. Voltage codes can be caused by sensors that are bad and stuck lean or rich. These codes can also be caused by lean or rich running conditions. The case studies we will focus on will look at pre-cat oxygen sensor codes, both caused by parts other than the O2 sensors.
Small Size, Vital Component – Throttle Position Sensor
The powertrain control module (PCM), which controls virtually every function of the engine and automatic transmission, depends upon an input signal from the TPS (among other things) to calculate fuel delivery and ignition timing strategy.
