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.

Transmission fluid temperature sensor "A" circuit
Description
The automatic transmission fluid (atf) temperature sensor converts the atf

The ecm applies a voltage to the temperature sensor through ecm terminal tho1.
The sensor resistance changes with the atf temperature. ...
