1, 2 and 3 Digit Codes: 113

Scan Tool 113 (MIL 31):

Trouble Code Number
- Scan tool 113
- General scan tool P0441
- MIL 31

Fault Message
- Evaporative Purge Flow Monitor Failure

Background
- This is a functionality test.
- If the fuel control doesn't sense purge vapor flow from the canister, this code will be set.

Range of Check
- Difference between the long-term adaptive memory values (fuel injection compensation value) is less than 5 % shift injector pulse width when the evaporative purge solenoid is turned on and off.
- Engine speed: less than 2,048 r/min.
- MAP sensor output voltage: 1.38-2.0 V
- MAP sensor value pressure right after ignition switch ON: less than 87 kPa (12.6 psi)
- Vehicle speed: 28-48 mph (45-77 km/h)
- Driving at a constant speed
- The above conditions continue for at least 1 minute.

Set Condition
- There is little difference (1 failed count) between the MAP sensor output voltages (on the average for 2 seconds) when the evaporative purge solenoid is turned on and off.
- Failures counted exceed 6 times while engine starts and then stops.

Probable Cause
- Purge line clogged
- Vacuum hose failed
- Evaporative purge solenoid failed
- Evaporative emission canister clogged
