ABSTRACT:
An exhaust backpressure tester is provided for determining exhaust backpressure in an exhaust system of an internal combustion engine of a motor vehicle. The tester includes a pressure sensor associated with the exhaust system for sensing pressure therein and generating a first signal representative thereof. A comparator is also provided and is connected to the pressure sensor for receiving the first signal, generating a second signal having a value which is representative of substantially zero backpressure in the exhaust system, processing the first signal to compensate it relative to the second signal, and comparing the processed first signal to the second signal to generate a pressure signal which is indicative of the exhaust backpressure in the exhaust system.
