P0010
FA20 ENGINE CONTROL: SFI SYSTEM: P0010, P0020; Camshaft Position "A" Actuator Circuit (Bank 1); 2013 MY FR-S [03/2012 -]
P0010 - Camshaft Position "A" Actuator Circuit (Bank 1)
P0020 - Camshaft Position "A" Actuator Circuit (Bank 2)
DESCRIPTION
Refer to P000A P000A.
MONITOR DESCRIPTION
This DTC is designed to detect open or short in the camshaft timing oil control valve (for intake camshaft) circuit. If the camshaft timing oil control valve's duty-cycle is excessively high while the engine is running, the ECM will illuminate the MIL and store the DTC.

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
CONFIRMATION DRIVING PATTERN
1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON and turn the Techstream on.
3. Clear DTCs (even if no DTCs are stored, perform the clear DTC operation) Reading and Clearing Diagnostic Trouble Codes.
4. Turn the ignition switch off and wait for at least 30 seconds.
5. Turn the ignition switch to ON and turn the Techstream on.
6. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.
7. With the vehicle stationary, depress the accelerator pedal and maintain an engine speed of between 2500 and 3000 rpm for 40 seconds or more [A].
8. Drive the vehicle at 10 km/h (6.25 mph) or more for 1 minute or more [B].
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
9. Enter the following menus: Powertrain / Engine / Trouble Codes.
10. Read pending DTCs.
HINT
* If a pending DTC is output, the system is malfunctioning.
* If a pending DTC is not output, perform the following procedure.
11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
12. Input the DTC: P0010 or P0020.
13. Check the DTC judgment result.
HINT
* If the judgment result shows NORMAL, the system is normal.
* If the judgment result shows ABNORMAL, the system has a malfunction.
14. If the test result is INCOMPLETE or N/A and no DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
HINT
* If a permanent DTC is output, the system is malfunctioning.
* If no permanent DTC is output, the system is normal.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT
* If DTC P0010 is displayed, check the intake camshaft circuit for the right bank VVT system (bank 1).
* If DTC P0020 is displayed, check the intake camshaft circuit for the left bank VVT system (bank 2).
* Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. READ DTC OUTPUT
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTC after recording the freeze frame data and DTC.
(e) Turn the ignition switch off.
(f) Start the engine and allow the engine to idle.
(g) Enter the following menus: Powertrain / Engine / Trouble Codes.
(h) Read DTCs.

B -- CHECK FOR INTERMITTENT PROBLEMS Check For Intermittent Problems
A -- Continue to next step.
2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE (FOR INTAKE CAMSHAFT)
(a) Inspect the camshaft timing oil control valve (for intake camshaft) Inspection.
NG -- REPLACE CAMSHAFT TIMING OIL CONTROL VALVE (FOR INTAKE CAMSHAFT) Removal
OK -- Continue to next step.
3. CHECK TERMINAL VOLTAGE (POWER SOURCE OF CAMSHAFT TIMING OIL CONTROL VALVE)
(a) Disconnect the camshaft timing oil control valve (for intake camshaft connector).
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
NG -- INSPECT RELAY (EFI MAIN1)
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - ECM)
(a) Disconnect the camshaft timing oil control valve (for intake camshaft connector).
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for open):
Standard Resistance (Check for short):
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ECM Removal
5. INSPECT RELAY (EFI MAIN1)
(a) Inspect EFI MAIN1 relay Testing and Inspection.
NG -- REPLACE RELAY (EFI MAIN1)
OK -- Continue to next step.
6. CHECK WIRE HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE - EFI MAIN1 RELAY)
(a) Disconnect the ECM connector.
(b) Remove the EFI MAIN1 relay from the engine room relay block assembly.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for open):
Standard Resistance (Check for short):
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- CHECK ECM POWER SOURCE CIRCUIT ECM Power Source Circuit
