1995 Toyota Previa ProblemsCheck Engine Light Due to Restricted 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.
At higher mileages (125,00+) the Engine Coolant Temperature Sensor may intermittently stop working, especially when the vehicle is fully warmed up. This can result in illumination of the Check Engine Light and/or an engine stalling problem.
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.
1995 Toyota Previa QuestionsCat converter compatibility (1 answer)
Replacing a cat converter on this van! The Aftermarket item I am looking at says OBDII compatible...will this cat converter still work with the Old OBDI diag SYSTEM?? The O2 sensors are the interface with the OBDI diag SYSTEM sooo it shouldn't make any difference to the Actual Hardware...same...
also the ob light is blinking on/off. one of the 2 fault codes says" Shift Solenoid E", Question are those solenoids or sensors located inside the transmission?. Transmission is operating normal don't feel anything wrong with it... Thanks. Rene.
