Toyota RAV4 Service Manual: Inspection
- Inspect no. 1 Chain tensioner
- Check that the plunger moves smoothly when the ratchet pawl is raised with your finger.
- Release the ratchet pawl, then check that the plunger is locked in place by the ratchet pawl and does not move when pushed with your finger.
- Inspect chain sub-assembly
- Using a vernier caliper, measure the length of the 16 links with the chain fully stretched.
Maximum chain elongation: 122.6 Mm (4.827 In.)
If the chain elongation is greater than the maximum, replace the chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect no. 2 Chain sub-assembly
- Using a vernier caliper, measure the length of the 8 links with the chain fully stretched.
Maximum chain elongation: 52.4 Mm (2.063 In.)
If the chain elongation is greater than the maximum, replace the no. 2 Chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect chain tensioner slipper
- Using a vernier caliper, measure the tensioner slipper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the chain tensioner slipper.
- Inspect no. 1 Chain vibration damper
- Using a vernier caliper, measure the vibration damper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the no. 1 Chain vibration damper.
- Inspect crankshaft timing sprocket
- Wrap the chain around the timing sprocket.
- Using a vernier caliper, measure the timing gear diameter with the chain.
Minimum gear diameter (with chain): 51.6 Mm (2.031 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the chain sub-assembly and crankshaft timing sprocket.
- Inspect oil pump drive sprocket
- Wrap the chain around the drive sprocket.
- Using a vernier caliper, measure the drive gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive sprocket.
- Inspect oil pump drive shaft sprocket
- Wrap the chain around the drive shaft sprocket.
- Using a vernier caliper, measure the drive shaft gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive shaft sprocket.

Oxygen (a/f) sensor signal stuck
Hint:
Although the dtc titles say oxygen sensor, these dtcs relate to the
air-fuel ratio (a/f) sensor.
Sensor 1 refers to the sensor mounted in front of the three-way
catalytic converter (twc) and
located near the engine assembly.
Description
The a/f sensor generates a voltage* ...
Correct driving posture
Adjust the angle of the seatback
so that you are sitting
straight up and so that you do
not have to lean forward to
steer.
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel.
Lock the head ...
Compressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning
amplifier. If the ratio of the
compressor speed divided by the engine speed is smaller than a predetermined
value, the air conditioning
amplifier turns the compressor off, and the indicator blinks at appro ...
