Typical Diagnostic Reference Values: Notes

An attempt is made to provide as much information as possible; some vehicles may not display all input and output signals.

Reference values may vary 20% depending on operating conditions, engine load, temperature, altitude, vehicle speed and other factors. RPM values are axle and tire dependent. Refer to PARAMETER IDENTIFICATION (PID) , for PID descriptions.

Values are taken at an altitude of approximately 600 ft above sea level.

Refer to the Introduction Section, ACRONYMS AND DEFINITIONS for technical terms applicable to Ford Motor Company products.

For detailed transmission diagnostics, refer to appropriate TRANSMISSION article.

Footnotes are referenced throughout the Typical Diagnostic Reference Value Charts. A letter in parentheses next to a value indicates supplemental information is applicable.

1. 1 volt equals 4.5 MPa (652 psi) and 4.45 volts equals 28 MPa (4061 psi)
2. 4.9 volts equals -40°C (-40°F) and 0.5 volts equals 100°C (212°F)
3. 4.3 volts equals 0°C (32°F) and 2.5 volts equals 50°C (122°F)
4. 0 volts equals disengaged and battery voltage equals engaged
5. CT equals 0.8 - 1.1 volts and WOT equals 3.1 - 3.5 volts
6. CT equals 3.9 - 4.2 volts and WOT equals 0.7 - 1.2 volts
7. CT equals 1.4 - 1.6 volts and WOT equals 3.6 - 4.1 volts
8. 1.35 volts equals 103 kPa (14.9 psi) and 4.5 volts equals 300 kPa (43.5 psi)
