DRIVE CYCLES 

OBD-II DRIVE CYCLE DESCRIPTION 

The following procedure is designed to execute and complete the OBD-II monitors and to clear the Ford P1000, 
I/M readiness code. To complete a specific monitor for repair verification, perform OBD-II DRIVE CYCLE 
VEHICLE PREPARATION, then continue with the procedure described by the appropriate monitor. EVAP 
monitor will not activate if ambient air temperature outside is not 40-100°F (4-38°C), or vehicle is above 8000 
feet. If DTC P1000 has to be cleared when ambient air temperature outside is not 40-100°F (4-38°C), or vehicle 
is above 8000 feet, PCM must detect these conditions once (twice on some models) before EVAP monitor can 
be "by-passed" and DTC P1000 will clear. Perform EVAP MONITOR "BY-PASS" PROCEDURE. 

All OBD-II drive cycles must be performed using scan tool. Consult scan tool manufacturer's instruction 
instruction for drive cycle procedure. Vehicle should be driven at steady speeds during cruise or acceleration to 
help complete OBD-II monitors. Operate engine throttle in a steady fashion to minimize time required for 
monitor completion. EVAP monitor only operates during first 30 minutes of engine run time. If performing 
EVAP monitor procedure, drive vehicle at a steady rate and at part throttle to minimize possible "fuel slosh". 

OBD-II DRIVE CYCLE VEHICLE PREPARATION 

OBD-II drive cycle is designed to execute and complete OBD-II monitors and clear DTC P1000. Ensure level 
in fuel tank is between 1/2-3/4 full. A 3/4 full tank is preferable. Use the following procedures to complete a 
specific monitor and record for repair verification:  

1. Install scan tool. Turn ignition switch to ON position. Cycle ignition switch off, then on. Using scan tool, 

select vehicle and engine. Clear DTCs and perform a PCM reset. See CLEARING CODES under SELF-
DIAGNOSTIC SYSTEM.  

2. Using scan tool, access PCM PIDs: ECT, EVAPDC, FLI (if available) and TP MODE from PID/DATA 

MONITOR & RECORD menu. Start engine. DO NOT turn ignition switch to OFF position. Allow 
engine to idle for 15 seconds. Drive at 40 MPH until ECT PID is at least 170°F (77°C).  

3. If IAT PID is 40-100°F (4-38°C), perform appropriate MONITOR drive cycle(s). See OBD-II DRIVE 

CYCLE. If IAT PID is not 40-100°F (4-38°C), perform appropriate monitor drive cycle(s), ensuring 
EVAP MONITOR BY-PASS drive cycle is performed to clear DTC P1000.  

OBD-II DRIVE CYCLE 

HO2S Monitor Procedure 
 
To activate HO2S monitor, ensure OBD-II DRIVE CYCLE VEHICLE PREPARATION has been 
performed. Drive vehicle at 40 MPH for at least 5 minutes. 

NOTE:

Rough road conditions may prevent certain steady state conditions and steady 
accelerations from validating the transmission and load related monitors. On 
models with Power Take-Off (PTO), disengage PTO system before performing 
drive cycle.

EVAP Monitor Procedure 
 
To activate EVAP monitor when IAT PID is within 40-100°F (4-38°C), drive vehicle at 45-65 MPH for 
10 minutes. Avoid sharp turns and hills. TP MODE PID should not exceed Part Throttle (PT), EVAPDC 
PID must be more than 75 percent, and FLI PID must be 15-85 percent. 

Catalyst Monitor Procedure 
 
To activate catalyst monitor, drive vehicle in stop and go traffic. Include 5 different constant cruise 
speeds, ranging from 20-70 MPH over a 10 minute period. 

EGR Monitor Procedure 
 
To activate EGR monitor, drive vehicle from a stop and accelerate to 45 MPH. Throttle position must be 
1/2-3/4. Repeat this procedure 3 times. 

SEC AIR/Comprehensive Component Monitor Engine Procedure 
 
To activate ISC portion of Comprehensive Component Monitor (CCM), bring vehicle to a stop. Allow 
engine to idle with transmission in Drive (A/T) or Neutral (M/T) for 2 minutes. 

Comprehensive Component Monitor Transmission Procedure 
 
To activate transmission portion of Comprehensive Component Monitor (CCM) monitor on M/T models, 
accelerate from 0 to 50 MPH, then perform MISFIRE & FUEL MONITOR PROCEDURES. On A/T 
models, drive vehicle in Overdrive from a stop, and accelerate to 50 MPH. Drive vehicle at 50 MPH for 
at least 15 seconds. Bring vehicle to a stop. Cancel Overdrive. Accelerate vehicle from stop to 40 MPH. 
Maintain speed for at least 30 seconds. Activate Overdrive and accelerate to 50 MPH. Maintain 50 MPH 
for at least 15 seconds. Bring vehicle to a stop and wait at least 20 seconds. Repeat this procedure 5 times. 

Misfire & Fuel Monitor Procedures 
 
To activate misfire and fuel monitors, accelerate vehicle from a stop to 65 MPH. Without applying brake 
pedal, allow vehicle to decelerate with throttle closed to 40 MPH. Repeat this procedure 3 times. 

Readiness Check Monitor 
 
To perform readiness check, access On-Board System Readiness test mode on scan tool. See ON-
BOARD SYSTEM READINESS (OSR) TEST MODE. Ensure that all non-continuous monitors have 
been completed. If all non-continuous monitors have not been completed, go to PENDING CODE 
CHECK & EVAP MONITOR "BY-PASS" CHECK. 

Pending Code Check & EVAP Monitor "By-pass" Check 
 
This procedure is used to determine if a pending code is preventing DTC P1000 from being cleared. 
Using scan tool, check for pending codes. If DTCs are present, perform normal repair procedures for any 
pending code concern. See DIAGNOSTIC TROUBLE CODE DEFINITIONS. If no DTCs are present,

repeat any incomplete monitor procedure. If EVAP monitor is not complete and IAT is not within 40-
100°F (4-38°C), or vehicle is above 8000 feet, perform EVAP MONITOR "BY-PASS" PROCEDURE. 

EVAP Monitor "By-pass" Procedure 
 
Leave scan tool connected and allow vehicle to sit overnight. Vehicle must be parked for more than 8 
hours. Perform steps 2 and 3 under OBD-II DRIVE CYCLE VEHICLE PREPARATION. DO NOT 
repeat step 1) . Repeat HO2S MONITOR through READINESS CHECK MONITOR procedures.
