1A-144 Engine Control System (4HK1)
DTC P0219 (Flash Code 543)
Circuit Description
The crankshaft position (CKP) sensor is located on the
flywheel housing. The ECM calculates the engine
speed and exact position of the crankshaft based on
the signal pulse from the CKP sensor. If the ECM
detects an engine overrun condition, this DTC will set.
Condition for Setting the DTC
• The ECM detects that the engine speed is more
than 3700RPM.
Action Taken When the DTC Sets
• The ECM will not illuminate the MIL or SVS lamp.
Refer to DTC Type Definitions for Action Taken
When the DTC Sets - Type D. (Euro 4
specification)
• The ECM illuminates the MIL when the diagnostic
runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
(Except Euro 4 specification)
Condition for Clearing the DTC
• Refer to DTC Type Definitions for Condition for
Clearing the DTC - Type D. (Euro 4 specification)
• Refer to DTC Type Definitions for Condition for
Clearing the MIL/ DTC - Type A. (Except Euro 4
specification)
Diagnostic Aids
• Make sure the CKP sensor is tight and the sensor
rotor teeth are not damaged.
• Electromagnetic interference in the CKP sensor
circuits may set this DTC.
• The Total Engine Overspeed Events parameter on
the scan tool indicates number of overrun events.
Notice: This DTC is caused by an engine overspeed
condition, which was most likely caused by driver error
(i.e. downshifting a manual transmission on a steep
grade). Since the DTC does not illuminate any lamps,
clear the DTC and ensure there are no sign of engine
damage. Excessive engine overspeed may damage
internal engine components.
Circuit/ System Testing DTC P0219
Step Action Value(s) Yes No

Did you perform the Diagnostic System Check
- Engine Controls?

Go to Step 2
Go to Diagnostic

Important: If DTC P0335 or P0336 is set, diagnose
that DTC first.
1. Install a scan tool.
2. Start the engine.
3. Observe the Engine Speed parameter with a
scan tool.
4. Accelerate the engine as necessary.
Does the Engine Speed parameter ever
exceed the specified value?
3700 RPM
Go to Step 4 Go to Step 3
3
Ask the driver if overrun is caused by gear slip-out,
shift error, down-slope driving, etc. If engine
overrun has experienced, the engine must be
inspected and repaired as necessary.
