- Turn the ignition switch to ON and turn the Techstream on [A].
- Wait for 5 seconds after turning the ignition switch to ON.
- Operate the accelerator pedal in accordance with the following procedure [B]. Enter the following menus: Powertrain / Engine and ECT / Data List / Gas Throttle / Accel Sens. No. 1 Volt %, and Accel Sens. No. 2 Volt %. Slowly depress the accelerator pedal until Accel Sens. No. 1 Volt % is approximately 30% and Accel Sens. No. 2 Volt % is approximately 46%, then slowly release the accelerator pedal.
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [C].
- Read the pending DTCs. HINT: If a pending DTC is output, the system is malfunctioning. If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
- Input the DTC: P2121.
- Check the DTC judgment result. Techstream Display Description NORMAL DTC judgment completed System normal ABNORMAL DTC judgment completed System abnormal INCOMPLETE DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions N/A Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit HINT: If the judgment result shows NORMAL, the system is normal. If the judgment result shows ABNORMAL, the system has a malfunction. If the judgment result shows INCOMPLETE or N/A, perform steps [B] and [C] again.
- If no pending DTC is output, perform a universal trip and check for permanent DTCs. Refer to «DTC CHECK / CLEAR [08/2013 - ]»(ref-635448-S28277682012014070300000) HINT: If a permanent DTC is output, the system is malfunctioning. If no permanent DTC is output, the system is normal.
FAIL-SAFE
The accelerator pedal position sensor has 2 (main and sub) sensor circuits. If the ECM detects an abnormal signal voltage difference between the 2 sensor circuits it switches to fail-safe mode. If the either of the 2 sensor circuits malfunctions, the ECM limits the engine output. If both of the circuits malfunction, the ECM regards the accelerator pedal as being released. In this case, the throttle valve remains closed as if the engine is idling.
If a pass condition is detected and then the ignition switch is turned off, the fail-safe operation stops and the system returns to normal.
CAUTION / NOTICE / HINT
HINT
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.

Note. In the EVAP system of this vehicle, turning on the vent valve does not seal off the EVAP system. To check for leaks in the EVAP system, disconnect the air inlet vent hose and apply pressure from the atmospheric side of the canister.
While the engine is running, if a predetermined condition (closed-loop, etc.) is met, the purge VSV is opened by the ECM and fuel vapors stored in the canister are purged to the intake manifold. The ECM changes the duty cycle ratio of the purge VSV to control purge flow volume.
The purge flow volume is also determined by the intake pressure. Atmospheric pressure is allowed into the canister through the vent valve to ensure that the purge flow is maintained when negative pressure (vacuum) is applied to the canister.
The following two monitors run to confirm appropriate EVAP system operation.
Scheme 113
Scheme 114
Scheme 115
Scheme 116
- Key-off Monitor This monitor checks for EVAP (evaporative emission) system leaks and canister pump module malfunctions. The monitor starts 5 hours* after the ignition switch is turned off. At least 5 hours are required for the fuel to cool down to stabilize the EVAP pressure, thus making the EVAP system monitor more accurate. The leak detection pump creates negative pressure (vacuum) in the EVAP system and the pressure is measured. Finally, the ECM monitors for leaks from the EVAP system, and malfunctions in both the canister pump module and purge VSV based on the EVAP pressure. HINT: *: If the engine coolant temperature is not less than 35°C (95°F) 5 hours after the ignition switch is turned off, the monitor check starts 2 hours later. If it is still not less than 35°C (95°F) 7 hours after the ignition switch is turned off, the monitor check starts 2.5 hours later.
- Purge Flow Monitor The purge flow monitor consists of the 2 monitors. The 1st monitor is conducted every time and the 2nd monitor is activated if necessary. The 1st monitor While the engine is running and the purge VSV (Vacuum Switching Valve) is on (open), the ECM monitors the purge flow by measuring the EVAP pressure change. If negative pressure is not created, the ECM begins the 2nd monitor. The 2nd monitor The vent valve is turned on (closed) and the EVAP pressure is then measured. If the variation in the pressure is less than 0.15 kPa(gauge) [1.125 mmHg(gauge)], the ECM interprets this as the purge VSV being stuck closed, illuminates the MIL and stores DTC P0441 (2 trip detection logic). Atmospheric pressure check: In order to ensure reliable malfunction detection, the variation in atmospheric pressure, before and after of the purge flow monitor, is measured by the ECM. *1 Canister *2 to Intake Manifold *3 ECM *4 Soak Timer *5 Purge VSV (On) *6 Fuel Cap *7 Canister Filter *8 Fuel Tank *9 Leak Detection Pump (Off) *10 Canister Pressure Sensor *11 Reference Orifice (0.02 inches) *12 Vent Valve (Off) *13 Canister Pump Module - - *a EVAP Purge Flow - - Component Operation Canister Contains activated charcoal to absorb EVAP (Evaporative Emissions) generated in fuel tank.

To ensure accurate EVAP monitor, measures 5 hours (+/-15 min) after ignition switch is turned off. This allows fuel to cool down, stabilizing EVAP pressure. When approximately 5 hours elapsed, ECM activates see scheme 3 Canister pump module Consists of (a) to (d) below. Canister pump module cannot be disassembled. (a) Vent valve Vents and closes EVAP system. When ECM turns valve on, EVAP system is closed. When ECM turns valve off, EVAP system is vented. Negative pressure (vacuum) is created in EVAP system to check for EVAP leaks by closing purge VSV, turning on vent valve (closing it) and operating leak detection pump (Scheme 101) (b) Canister pressure sensor Indicates pressure as voltages. ECM supplies regulated 5 V to pressure sensor, and uses feedback from sensor to monitor EVAP system pressure see scheme 2 (c) Leak detection pump Creates negative pressure (vacuum) in EVAP system for leak check. (d) Reference orifice Has opening with 0.02 inch diameter. Vacuum is produced through orifice by closing purge VSV, turning off vent valve and operating leak detection pump, to monitor reference pressure. Reference pressure is used when checking for small EVAP leaks. *1 Canister *2 Reference Orifice (0.02 Inch) *3 Canister Pressure Sensor - - *a Canister Pump Module (Scheme 101) *b Airflow *c Condition: Purge Flow *d Condition: Leak Check *e Vent Valve: off (vent) *f to Canister Filter (Atmosphere) *g Leak Detection Pump: off *h Vent Valve: on (closed) *i Leak Detection Pump: on
Note. Inspect the fuses for circuits related to this system before performing the following procedure. The Techstream is required to conduct the following diagnostic troubleshooting procedure.
HINT
- Using the Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
- 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.
HINT
After a repair, check Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow Monitor Confirmation described below.

Inspection Method
Example
Drive at 10 km/h (6.25 mph), depress the accelerator pedal by 1/2 to 3/4 and keep it in that position. Under these conditions, if the engine speed decreases to 1000 RPM when the brake pedal is depressed, then the brake override system has been activated.
| WARNING | When carrying out the inspection, use a place where you are able to carry it out safely and also pay close attention to your surroundings. Also, when driving make absolutely sure that all road traffic laws, such as speed limits, are observed. |
HINT
- Under normal conditions, the Accelerator Position value changes in response to the Accel Sens. No. 1 Volt % value. For more information on the numerical values, refer to the Data List. Refer to «DATA LIST / ACTIVE TEST [08/2013 - ]»(ref-635448-S04095086102014070300000)
- If the Accelerator Position and Accel Sens. No. 1 Volt % values in the Data List diverge and the Accelerator Position value in the Data List is fixed even though Accel Sens. No. 1 Volt % is changing, check that this control is activated (use the Techstream data saving function to record data while driving the vehicle and then confirm it after driving is completed).
Note. The brake override system restricts driving torque if the brake pedal is depressed when driving with the accelerator pedal depressed. If a customer reports experiencing loss of torque after the accelerator and brake pedals have both been intentionally depressed, explain to the customer that this is not a malfunction, and that the customer should avoid depressing both the accelerator and brake pedals at the same time. Example: While operating the accelerator pedal, the customer uses their left foot to operate the brake pedal.
