This manual does not include all the necessary items about repair and service. This manual is made
for the purpose of the use for the persons who have special techniques and certifications. In the
cases that non--specialized or uncertified technicians perform repair or service only using this manu-
al or without proper equipment or tool, that may cause severe injury to you or other people around
and also cause damage to your customer's vehicle.
In order to prevent dangerous operation and damages to your customer's vehicle, be sure to follow
the instruction shown below.
Must read this manual thoroughly. It is especially important to have good understanding all the
S
contents written in the PRECAUTION of "IN" section.
The service method written in this manual is very effective to perform repair and service. When
S
performing the operations following the procedures using this manual, be sure to use tools spe-
cified and recommended. If using non--specified or recommended tools and service method,
be sure to confirm safety of the technicians and any possibility of causing personal injury or
damage to the customer's vehicle before starting the operation.
If part replacement is necessary, must replace the part with the same part number or equivalent
S
part. Do not replace it with inferior quality.
It is important to note that this manual contains various "Cautions" and "Notices" that must be
S
carefully observed in order to reduce the risk of personal injury during service or repair, or the
possibility that improper service or repair may damage the vehicle or render it unsafe. It is also
important to understand that these "Cautions" and "Notices" are not exhaustive, because it is
important to warn of all the possible hazardous consequences that might result from failure to
follow these instructions.

Questions and answers
Como ligar o distribuidor do motor 1rz
To connect the distributor for a Toyota 1RZ engine:
1. Ensure the engine is at normal operating temperature.
2. Connect a tachometer to terminal IG⊖ of the check connector. Do not let the terminal touch the ground.
3. Use SST (Special Service Tool) 09843–18020 to connect terminals TE1 and E1 of the check connector.
4. Use a timing light to check ignition timing (should be 5° BTDC at idle).
5. If adjustment is needed, loosen the two distributor mounting bolts and turn the distributor to adjust timing.
6. Tighten the bolts to 20 N·m (14 ft·lbf).
7. Remove SST from the check connector.
Ensure compatibility of tools with the ignition system before use.

Engine not having full combustion, loss of power and blackening plugs
A Toyota engine with part number 1RZ experiencing incomplete combustion, loss of power, and blackened spark plugs could be caused by the following issues:
1. Ignition Problems – Faulty ignition coil, igniter, or spark plugs can lead to weak or no spark, causing incomplete combustion. (Referenced in DI--151, IG--1)
2. Injector Circuit Malfunction – A faulty injector or injector circuit may cause excessive fuel delivery, leading to rich fuel mixture and blackened spark plugs. (Referenced in DI--158)
3. Airflow Meter Circuit Issues – A malfunctioning airflow meter can provide incorrect air intake readings, leading to an improper air-fuel mixture. (Referenced in DI--94)
4. Fuel Pump Control Circuit Fault – A malfunction here can result in incorrect fuel pressure, affecting combustion efficiency. (Referenced in DI--174)
5. Variable Resistor Circuit Malfunction – If applicable, this can affect sensor inputs to the ECU, leading to improper fuel delivery. (Referenced in DI--183)
6. Engine ECU Malfunction – A faulty ECU can cause incorrect fuel injection timing and mixture. (Referenced in DI--170)
These issues can lead to an overly rich fuel mixture, causing blackened spark plugs, reduced power, and inefficient combustion.

1rz engine can't pick up fast and sounds as if not enough fuel reaching the engine
A Toyota 1RZ engine with slow acceleration and symptoms of insufficient fuel may have issues related to the fuel injection system, ignition system, or air intake. Possible causes include:
1. Fuel Injection Issues – Clogged or malfunctioning fuel injectors can reduce the amount of fuel delivered to the engine, leading to poor acceleration.
2. Fuel Pressure Problems – A weak or failing fuel pump, clogged fuel filter, or faulty fuel pressure regulator can restrict fuel flow.
3. Ignition System Faults – A weak spark due to worn spark plugs, faulty ignition coils, or incorrect ignition timing can affect combustion efficiency.
4. Airflow Restrictions – A dirty or clogged air filter or a malfunctioning throttle body can limit the amount of air entering the engine.
5. Sensor Malfunctions – A faulty mass airflow sensor (MAF), throttle position sensor (TPS), or engine coolant temperature sensor can send incorrect signals to the ECU, affecting fuel delivery and timing.
6. Starter Signal Circuit Issues – If the starter signal is not properly received by the ECU, it may affect the fuel injection control, leading to poor performance.
7. Knock Sensor Issues – A malfunctioning knock sensor or related wiring problems could cause the ECU to retard ignition timing, reducing power.
A proper diagnostic check using an electrical tester and oscilloscope can help identify the exact fault.
