The P2135 code indicates that the engine control module (ECM) has detected a mismatch between the voltage signals of Throttle Position Sensor (TPS) A and TPS B (image below). These dual sensors work ...

I'm considering swapping one of the newer GM direct-injected 4.3L V-6 engines into my TJ. The stock GM system controls the fuel pump with pulse width modulation (PWM). Do you know if I can run the ...

Modern automotive systems use serial data transmissions to enable the rapid transfer of information. Single edge nibble transmission (SENT) bus, a serial data standard managed by SAE International, is ...

Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

Interesting question. Before we could really answer it, we had to read up on pulse width modulation and why virtually all of the OEs now use PWM to control their fuel systems. To be clear, we will ...
