2005 MY OBD System Operation Summary for Gasoline Engines

!#6! ;The MIL is illuminated for all emissions related electrical component malfunctions. For malfunctions attributable toa mechanical component (such as a clutch, gear, band, valve, etc.), some transmissions are capable of notcommanding the mechanically failed component and providing the remaining maximum functionality (functionalityis reassessed on each power up)- in such case a non-MIL Diagnostic Trouble Code (DTC) will be stored and, ifso equipped, a Transmission Control Indicator Light (TCIL) will flash.;Transmission Range Sensor Check Operation:DTCsMonitor executionMonitor SequenceSensors OKMonitoring DurationP0708, P0705 Open/invalid pattern for digital TRSP0707, P0708 Opens/shorts for analog TRSP0705 Out of range signal frequency for PWM TRSP0706, P0707 Low /High duty cycle for PWM TRSP0705 Open/invalid pattern for 4- bit digital TRS – 6HP26, CFT30P0707, P0708 Opens/shorts for dual analog TRS – F21P0706 Range/performance for dual analog TRS – F21ContinuousNoneUp to 30 seconds for pattern recognition, 5 seconds for analog faultsTypical TRS check entry conditions:Auto Transmission Entry Conditions Minimum MaximumGear selector position each position for up to 30 seconds 480 secondsTypical TRS malfunction thresholds:Digital TRS: Invalid pattern from 3 or 5 digital inputs and/or 1 analog circuit open for 5 seconds4-bit digital TRS: Invalid pattern for 200 msAnalog TRS: Voltage > 4.8 volts or < 0.2 volts for 5 secondsDual analog TRS: Voltage > 4.84 volts or < 0.127 volts for 200 ms orSum of both inputs is outside the range of 5.0 volts +/- 0.29 volts for 200 msPWM TRS: Frequency > 160 Hz or < 100 Hz,Duty Cycle > 90% or < 10%FORD MOTOR COMPANY REVISION DATE: APRIL 28, 2004 PAGE 89 OF 131
