POSSIBLE CAUSE

•  The level of accumulated water in the fuel filter exceeds the specification

•  Sedimentor switch connector or terminals malfunction

•  Short to ground in wiring harness between sedimentor switch terminal A and PCM terminal 2A

•  PCM connector or terminals malfunction

•  Sedimentor switch malfunction

•  PCM malfunction

DTC P1140:00	Sedimentor switch control circuit range/performance problem
DETECTION CONDITION	• The level of accumulated water in the fuel filter exceeds the specification (sedimentor switch turns on in this case). Diagnostic support note • This is an intermittent monitor (other). • The check engine light does not illuminate. • FREEZE FRAME DATA is not available. • Snapshot data is available. • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	• The level of accumulated water in the fuel filter exceeds the specification • Sedimentor switch connector or terminals malfunction • Short to ground in wiring harness between sedimentor switch terminal A and PCM terminal 2A • PCM connector or terminals malfunction • Sedimentor switch malfunction • PCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	DETERMINE IF MALFUNCTION CAUSE IS LEVEL OF ACCUMULATED WATER IN THE FUEL FILTER EXCEEDS THE SPECIFICATION • Perform the “FUEL FILTER WATER DRAINING”. (See FUEL FILTER WATER DRAINING [SKYACTIV-D 1.5].) • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Go to the next step.
3		No	Go to Step 9.
4	INSPECT SEDIMENTOR SWITCH CONNECTOR CONDITION • Switch the ignition off. • Disconnect the sedimentor switch connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
4		No	Go to the next step.
5	INSPECT SEDIMENTOR SWITCH CONTROL CIRCUIT FOR SHORT TO GROUND • Verify that the sedimentor switch connector is disconnected. • Inspect for continuity between sedimentor switch terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	Disconnect the PCM connector and inspect the wiring harness for short to ground. • If the short to ground circuit could be detected in the wiring harness: ― Refer to the wiring diagram and verify whether or not there is a common connector between sedimentor switch terminal A and PCM terminal 2A. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to ground. • If the short to ground circuit could not be detected in the wiring harness: ― Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].) Go to Step 8.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 8.
6		No	Go to the next step.
7	INSPECT SEDIMENTOR SWITCH • Inspect the sedimentor switch. (See SEDIMENTOR SWITCH INSPECTION [SKYACTIV-D 1.5].) • Is there any malfunction?	Yes	Replace the fuel filter, then go to the next step. (See FUEL FILTER REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].) Go to the next step.
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
9		No	DTC troubleshooting completed.
