Engine Control System (1GR-FE) (Diagnostic Codes (P0335-P1605): Diagnosis Toyota 4Runner V

INSPECTION PROCEDURE

HINT

1. After performing the inspection procedure for the crankshaft position sensor, if DTC P0335 is output again, check the following items related to the camshaft position sensor. Installation condition of the camshaft position sensor. Installation condition of the camshaft. Connection of the camshaft position sensor connector.
2. If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
3. Check the engine speed. The engine speed can be checked by using the Techstream. To check the engine speed, follow the procedure below: Connect the Techstream to the DLC3. Start the engine. Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed. The engine speed may be indicated as zero despite the crankshaft revolving 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.
4. Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. 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.

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 306

1. Connect the Techstream to the DLC3 (a).
2. Start the engine and warm it up with all the accessories switched off until the engine coolant temperature stabilizes (b).
3. Run the engine at an engine speed of between 2500 RPM and 3000 RPM for at least 3 minutes (c).
4. While running the engine at 3000 RPM for 2 seconds, and then 2000 RPM for 2 seconds, check the waveforms of the air fuel ratio and heated oxygen sensors using the Techstream (d).

HINT

1. If either voltage output of the air fuel ratio or heated oxygen sensor does not fluctuate, or there is noise in the waveform of either sensor, the sensor may be malfunctioning.
2. If the voltage outputs of both sensors remain lean or rich, the air-fuel ratio may be extremely lean or rich. In such cases, perform A/F Control using the Techstream.
3. 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).

HINT

1. In contrast to normal malfunction diagnosis for components, circuits and systems, DTCs P1603 and P1605 are used to determine the malfunctioning area from the problem symptoms and freeze frame data when the user mentions problems such as engine stall. As these DTCs can be stored as a result of certain user actions, even if these DTCs are output, if the customer makes no mention of problems, clear these DTCs without performing any troubleshooting and return the vehicle to the customer.
2. If any other DTCs are output, perform troubleshooting for those DTCs first.
3. Use any information from the customer problem analysis about the condition of the vehicle at the time when the problem occurred (how the engine stopped, conditions when the engine was restarted, etc.) as a reference. Symptom Suspected Area Engine vibration occurs and engine stops Air-fuel ratio abnormal Engine stops with no engine vibration Ignition system, injection stoppage, high load from external parts Engine can be started with accelerator pedal depressed Insufficient air volume Rough idling after engine started Air-fuel ratio abnormal, abnormal combustion
4. Read freeze frame data using the Techstream. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.
5. When confirming the freeze frame data, be sure to check all 5 sets of freeze frame data, refer to «FREEZE FRAME DATA»(ref-421952-S05337952652011092600000) .
6. When DTC P1603 (Engine Stall History) is stored, DTC P1605 (Rough Idling) is also stored. When confirming freeze frame data, check DTC P1605. The ECM stores DTC P1605 first. Therefore, 5 sets of freeze frame data can be confirmed through DTC P1605, enabling the technician to obtain more information.
7. When confirming freeze frame data, if there are multiple items related to the cause of the malfunction, perform troubleshooting for all related items.
8. Try to operate the vehicle under the conditions recorded in the freeze frame data which were present when the malfunction occurred. Confirm the data at this time and the data when the engine is idling (engine warmed up, no load, and shift lever in D or N) and compare these data with the freeze frame data.
9. Inspections take into account the fact that the malfunction may not have reoccurred and place emphasis on checking the vehicle conditions present at the time when the malfunction occurred.
10. When performing inspections, jiggle the relevant wire harnesses and connectors in an attempt to reproduce malfunctions that do not always occur.

1. If the engine stalled when the intake air volume was low (during idling or deceleration), there may be a decrease in torque due to an incorrect air-fuel ratio, etc.
2. If the engine stalled when the intake air volume was high (during driving or acceleration), there may be a major malfunction such as continuous misfire due to ignition stoppage, fuel injection stoppage, etc. and the torque drops to zero.

1. If the engine speed decreased slowly, there may have been a decrease in torque due to an air-fuel ratio that was incorrect (by approximately 20 to 30%), etc.
2. If the engine speed decreased rapidly, there may have been a malfunction such as when the engine misfires almost continuously due to ignition stoppage, fuel injection stoppage, etc., or when the external load increases due to an external part malfunctioning.

Otherwise, the engine speed is considered to have decreased slowly. In the freeze frame data, the decrease in engine speed from #3 to #5 is 400 RPM or more. In the freeze frame data, the engine speed at #5 is 120 RPM or less. If the vehicle speed is 30 km/h or less and the difference between Engine Speed and SPD (NT) is 100 RPM or less, inspect the automatic transmission. (Depending on the rate of vehicle deceleration, the engine speed may have decreased due to the A/T lock-up release being late.) *2: When a DTC is stored, feedback compensation increases because the air-fuel ratio is determined to be lean. *3: When a DTC is stored, feedback compensation decreases because the air-fuel ratio is determined to be rich. *4: This item should be checked when DTC P1603 is output and is not necessary to check when only P1605 is output.

HINT: If the accelerator pedal is released after racing the engine, the inspection is easier to perform because the vacuum inside the intake pipes increases and the air suction noise becomes louder. If Short FT and Long FT are largely different from the normal values when idling (the intake air volume is small) and almost the same as the normal values when racing the engine (the intake air volume is high), air leakage may be present.

Confirm the data at this time and the data when the engine is idling (engine warmed up, no load, and shift lever in D or N) and compare these data with the freeze frame data. *1: If the mass air flow meter is malfunctioning and incorrectly measures the pressure to be less than the actual intake manifold pressure, the freeze frame data will show a low engine load value. *2: If the air fuel ratio sensor is malfunctioning and constantly outputs a value indicating the air-fuel ratio is lean, the actual air-fuel ratio will become rich and the engine may stall.
