⁽¹⁾	Measure voltage between ground and ECM/PCM terminal No. in parentheses.

⁽²⁾	Voltage measurement should change gradually and smoothly as throttle is opened.

⁽³⁾	Test pins located on breakout box. See Fig 1 or Fig 4 .

⁽⁴⁾	For PCM connector pin identification, see Fig 2 .

⁽⁵⁾	Information not available from manufacturer.

⁽⁶⁾	Measure the resistance between TP sensor terminals "A" and "C" using an ohmmeter. See Fig 3 or Fig 4 .
