Having problems with your Toyota Pickup ?
Have check engine light coming on, 1988 toyota pickup, 22re engine, trouble code 71 EGR system. the EGR Valve is ok & working. IT also Efecks the temperature sometimes. Where shoud I look next?
The Thermo Sensor valve would be the next place to look. Since the EGR valve is ok, and your experiencing temp problems, the Thermo Sensor would make sense. Below is a diagram showing the layout and where the valve is. Before removing or replacing, check all the vacuum lines for leaks. It's possible the components are good but a pinhole in a vacuum line could throw a check engine light. Best of luck.
