1992 Toyota Previa Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1992 Toyota Previa

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.

Auto repair company says I need to replace mounts with shocks. Are they the same as the front strut mounts because that is all I can find online?

The most reliable car. I have had very few repairs. At 125,000 miles so far. Practically like new. No rust. I hope to have this car for another 17 years. Both kids grew up with this car. We are all very attached to it. My daughter went from car seat to drivers seat in this van. Its a winner!

Bought my 92 Previa LE new. Drove it 200k in 19 years. It rusted badly around wheel wells, door sills, and rear window seal area, due to salty Chicago area roads. Everything else ran strong! Sold it for $2500 in '11 and bought a rust-free 94 Previa LE with 135k from North Carolina for $4000. I always use Mobile 1 Synthetic oil. I just love these roomy and high mpg vans from Toyota...nothing...

not for texas :)
