Use the factory test sequence for intake leaks, power/grounds, signal voltage, harness and idle-control command. Match year, transmission, emissions/production detail and installed number before ordering.
OEM numbers
Checked 1995 MAF 22680-70F00 -> 22680-70F05. Checked TPS families include 22620-53F01 -> 22620-53F02 plus production/transmission-specific alternatives. Checked aftermarket IACV example Standard AC153.Supersession
The 1995 MAF revision is cataloged as 22680-70F00 -> 22680-70F05. The TPS catalog contains multiple applications, so 22620-53F01 -> 22620-53F02 must not be generalized without transmission and installed-number confirmation.
Fitment
Use the factory test sequence for intake leaks, power/grounds, signal voltage, harness and idle-control command. Match year, transmission, emissions/production detail and installed number before ordering.
Aftermarket options
OEM, remanufactured and aftermarket MAF/TPS/IACV paths exist. Speed-density or modified-intake conversions are outside stock replacement and require documented calibration.
Before you buy
A rough idle or hesitation does not identify one part. Test intake leaks, wiring, power/ground and sensor/control signals; match year, transmission and installed number before ordering a MAF, TPS or idle valve.
