Toyota Previa Problems

Failed Emissions Test Due to Blocked EGR System

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.

Lean Mass Air Flow Sensor Causing Code P0170

Occasionally, the mass air flow sensor can go lean and set a code P0170 for fuel system lean. This in not an oxygen sensor problem. If there are no vacuum leaks, the mass air flow sensor may need to be replaced. Our technicians remind us to use a factory part because the aftermarket rebuilds are very inconsistent.

Loss of Power on Highway Due to Internally Leaking Fuel Pulsation Dampener

A loss of power on the freeway may due to an internally leaking fuel pulsation dampener. This commonly occurs on higher mileage vehicles.

Toyota Previa Reviews

I bought my Toyota Previa new in 1990... a 1991 model. Since then, my children and I have put 489,000 miles on it. Today I learned that I may need a differencial. Other than that it's an amazing vehicle and I intend to replace the differencial...but I need to locate a used one somewhere. This will be the first major repair to my awesome vehicle. I love driving it just like I did when I drove it...
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...
I have a 1993 Previa with 190,000 miles and still going strong. One of the last rear wheel drive minivans on the road. Very durable and outlast its contemporaries on the road. My two boys grew up with it and they are now driving it too. Great car!
