Pinpoint Test B: P0117

P0117





TEST B: RETRIEVE DTCS

NOTE: Battery and or ECM disconnection prior to scanning will erase all data, ensure that the correct DTC is present.

Connect scan tool
Record DTC(s), freeze frame data and GO to [B2]





B2: CHECK ECT SENSOR OPEN CIRCUIT

Ignition switch to position 0
Disconnect PI004
Rear of top hose
Measure the resistance between the ECT sensor pins 1 and 2.
- Resistance > 30 k ohms?
Yes
Renew sensor and proceed to B6
No
GO to [B3]





B3: CHECK HARNESS CONTINUITY

Ignition switch to position 0
Disconnect EM011
Inside ECM housing
Disconnect PI004
Rear of top hose
Measure the resistance between the ECM connector EM011/009 and the ECT connector PI004/002.
- Is the resistance < 0.5 Ohms?
Yes
GO to [B4]
No
Inspect harness/connector EM011/009, PI004/002 and PI001/005 for corrosion, damage, bent or pushed back pins. Repair as necessary and test the system for normal operation.





B4: CHECK HARNESS CONTINUITY

NOTE: To avoid a spurious result, disconnect connectors PI042 and PI006 (electronic throttle body) and PI035 (MAP meter).

Ignition switch to position 0
Disconnect EM010
Inside ECM housing
Measure the resistance between the ECM connector EM011/012 and the ECT connector PI004/001.
- Is the resistance < 0.5 Ohms?
Yes
GO to [B5]
No
Inspect harness/connector EM011/012, PI004/001, PI001/006 and splices EMS02/PIS01 for corrosion, damage, bent or pushed back pins. Repair as necessary, reconnect all connectors. Test the system for normal operation.





B5: CHECK HARNESS CONTINUITY

NOTE: Do not reconnect electronic throttle body connectors PI042 and PI006.

Ignition switch to position 0
Disconnect EM010
Inside ECM housing
Measure the resistance between the ECM connector EM010/020 and the ECT connector PI004/001.
- Is the resistance < 0.5 Ohms?
Yes
GO to [B6]
No
Inspect harness/connector EM010/020, PI004/001, PI001/006 and splices EMS02/PIS01 for corrosion, damage, bent or pushed back pins. Repair as required and reconnect all connectors. Test the system for normal operation.





B6: CHECK FOR SHORT TO B+

Ignition switch to position 0
Disconnect EM011
Inside ECM housing
Ignition switch to position 11
Measure the voltage between pins 9 and 12 of the connector.
- Is the voltage > 1 V?
Yes
Inspect harness/connector EM011/009, PI004/002, PI001/005 and splices EMS02/PIS01 for corrosion, damage, bent or pushed back pins. Repair as required and reconnect all connectors. Test the system for normal operation.
No
GO to [B7]

B7: END
Perform appropriate service drive cycle and check for the presence of DTC.
- Has the fault code cleared?
Yes
STOP
No
