Engine Control (2GR-FE) (Diagnostic Codes (P0300-P1607): Diagnosis Toyota Venza I

INSPECTION PROCEDURE

HINT

1. If any DTCs other than misfire DTCs are output, troubleshoot those DTCs first.
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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
3. If the misfire does not recur when the vehicle is brought to the workshop, reproduce the conditions stored in the ECM as freeze frame data.
4. If the misfire still cannot be reproduced even though the conditions stored in the ECM as freeze frame data have been reproduced, one of the following factors is considered to be a possible cause of the problem: There was insufficient fuel volume in the tank. Improper fuel is used. The spark plugs have been contaminated.
5. After finishing repairs, check the misfire counts of the cylinders (Cylinder #1 Misfire Count to Cylinder #6 Misfire Count).
6. Be sure to confirm that no misfiring cylinder DTCs are set again by conducting the confirmation driving pattern after finishing repairs.
7. For 6 cylinder engines, the ECM intentionally does not set the specific misfiring cylinder DTCs at high engine speed. If misfires occur only in high engine speed areas, only DTC P0300 is set. In the event of DTC P0300 being present, perform the following operations: Clear the DTC. Refer to «DTC CHECK / CLEAR»(ref-394619-S02527777542011040800000) . Start the engine and conduct the confirmation driving pattern. Read the misfiring rates of each cylinder or DTC(s) using the Techstream. Repair the cylinder(s) that has a high misfiring rate or is indicated by the DTC. After finishing repairs, conduct the confirmation driving pattern again, in order to verify that DTC P0300 is not set.
8. When one of Short FT #1, Long FT #1, Short FT #2 or Long FT #2 in the freeze frame data is outside the range of +/-20%, the air fuel ratio may be Rich (-20% or less) or Lean (+20% or more).
9. When the Coolant Temp in the freeze frame data is less than 75°C (167°F), the misfires have occurred only while the engine is being warmed up.
10. An extremely imbalanced drive wheel which causes body vibration may cause misfire DTCs detection.

If no misfire counts occur in any cylinders, perform the following procedure: Start the engine and let it idle. Move the shift lever to D. Check the Cylinder #1 (to #6) Misfire Count. If misfire counts are still not displayed, perform steps "A" and "B". Drive the vehicle while satisfying the Misfire RPM and Misfire Load values noted in the "Read Value Using Techstream (Misfire RPM and Misfire Load)" procedure above. Read Cylinder #1 (to #6) Misfire Count or the DTCs displayed on the Techstream. Result Misfire Count Proceed to Most misfires occur in only 1 or 2 cylinders A 3 cylinders or more have equal misfire counts B HINT: If it is difficult to reproduce misfires for each cylinder, check the Data List item called Misfire Margin. Try to find vehicle driving conditions that lower the Misfire Margin value. Values above 30% are considered normal. If the Coolant Temp value of the freeze frame data is below 75°C (167°F), the misfire may be detected only when the engine is cold.

1. If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
2. Check the engine speed. The engine speed can be checked using the Techstream. Follow the procedure below: Connect the Techstream to the DLC3. Start the engine. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Data List / Engine Speed. The engine speed may be indicated as zero despite the engine rotating normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.
3. 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

CONDITIONING FOR SENSOR TESTING

HINT

Perform the operation with the engine speeds and time durations described below prior to checking the waveforms of the air fuel ratio and heated oxygen sensors. This is in order to activate the sensors sufficiently to obtain the appropriate inspection results.

Scheme 510

1. Connect the Techstream to the DLC3 (Step "A").
2. Start the engine and warm it up with all the accessories switched off, until the engine coolant temperature stabilizes (Step "B").
3. Run the engine at an engine speed of between 2500 rpm and 3000 rpm for at least 3 minutes (Step "C").
4. While running the engine at 3000 rpm and 2000 rpm for 2 seconds, check the waveforms of the air fuel ratio and heated oxygen sensors using the Techstream (Step "D"). HINT: If either of the voltage outputs of the air fuel ratio or heated oxygen sensor does not fluctuate, or either of the sensors makes a noise, the sensor may be malfunctioning. If the voltage outputs of both the sensors remain lean or rich, the air fuel ratio may be extremely lean or rich. In such cases, enter the following menus: Powertrain / Engine / Active Test / Control the Injection Volume for A/F Sensor. If the three-way catalytic converter has deteriorated, the heated oxygen sensor (located behind the three-way catalytic converter) voltage output fluctuates up and down frequently, even under normal driving conditions (active air fuel ratio control is not performed).

Scheme 512

Scheme 513

1. AIR FUEL RATIO CONTROL HINT: Malfunctioning areas can be identified by performing the Control the Injection Volume for A/F Sensor function provided in the Active Test. The Control the Injection Volume for A/F Sensor function can help to determine whether the air fuel ratio sensor, heated oxygen sensor and other potential trouble areas are malfunctioning. The following instructions describe how to conduct the Control the Injection Volume for A/F Sensor operation using the Techstream. Connect the Techstream to the DLC3. Start the engine. Turn the Techstream on. Warm up the engine at an engine speed of 2500 rpm for approximately 90 seconds. Enter the following menus: Powertrain / Engine / Active Test / Control the Injection Volume for A/F Sensor. Perform the Active Test operation with the engine in an idling condition (press the RIGHT or LEFT button to change the fuel injection volume). Monitor the voltage outputs of the air fuel ratio and heated oxygen sensors (AFS Voltage B1S1 and O2S B1S2 or AFS Voltage B2S1 and O2S B2S2) displayed on the Techstream. HINT: The Control the Injection Volume for A/F Sensor operation lowers the fuel injection volume by -12.5% or increases the injection volume by 25%. Each sensor reacts in accordance with increases and decreases in the fuel injection volume. Techstream Display (Sensor) Injection Volume Status Voltage AFS Voltage B1S1 or AFS Voltage B2S1 (Air fuel ratio) +25% Rich Less than 3.1 V AFS Voltage B1S1 or AFS Voltage B2S1 (Air fuel ratio) -12.5% Lean More than 3.4 V O2S B1S2 or O2S B2S2 (Heated oxygen) +25% Rich More than 0.55 V O2S B1S2 or O2S B2S2 (Heated oxygen) -12.5% Lean Less than 0.4 V NOTE: The air fuel ratio sensor has an output delay of a few seconds and the heated oxygen sensor has a maximum output delay of approximately 20 seconds.

To display the graph, enter the following menus: Powertrain / Engine / Active Test / Control the Injection Volume for A/F Sensor / A/F Control System / AFS Voltage B1S1 and O2S B1S2 or AFS Voltage B2S1 and O2S B2S2. 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
