- p1101 sets soon after resetting. after test drive also p0171, p0106, p0300 sets. fuel trims at 33% st and 34% LT at idle. seem good while accelerating and go lean again at a cruise speed. Found that the pcv check valve was ruptured and not in place and it is integral to the intake manifold. advise replacing the intake manifold. the pcv diaphragm in valve cover is also a high fail item and causes this same code and they often go hand in hand but this one is not testing ruptured at this time with the tissue test. Can retest this again after the intake is replaced. After replacing intake manifold the fuel trims still remained high at idle and set p0170 and p1101. advise replacing the valve cover and retesting. required one additional part duriing the valve cover repair. Fuel trims now staying near zero and verified the p0171 and p1101 would not reset while testing.
- When first test driving vehicle there was not a tpms light but as driving it began to flash and went solid has been on each time driving since.
