Toyota Avensis
Hi , I have a 2003 Toyota Avensis 1AZ-FE motor. The issue I am having is that the check engine light comes on and the engine will not rev. I have connected a scan tool. there was one code present and that was for low fuel pressure circuit. After a few more checks found that the high pressure pump was loosing its power supply. What could cause this ?


no real symptoms other than the check engine light. 160000 miles

Truck is a 4WD, V8 7.4L 454 CID Gas. I had a tune up done and there was a computer error code P0137. Tech said it was an Bank 1 Sensor 2 Oxygen sensor failure but the "Check Engine" light has never come on. The truck is a 1997 and has only 113,00 miles on it. Should I replace that sensor, and if so, where is it located? Before the tune up the truck was running and idling very rough and would shake. Gas mileage was really bad.

Sometimes when the car slows to a stop, the car dies. Idle set at 900 rpm. Car starts back right away.
