OK folks, my check engine light came on and I would like to know what to do. 1998 Sienna, 190K miles. Overall reliable vehicle. This may be 2 separate issues that coincidentally occurred, or they may be related. Please help me sort this out, thanks. I plan to take this on a camping trip for a 2.5 hour drive Friday. Without it I cannot pull the trailer....
A short bit of history first. Son went to work and called saying that the car is dead there. There has been no indication of anything going wrong before that; this was a sudden event. It had no response to turning the key after sitting for maybe 2-3 hours. I arrived in the Jeep and jump started it. It was really dead - I had to let it sit there and suck juice from the Jeep for a while for it to turn fast enough (meaning do more than just clicking). Then it started up and seemed fine. I don't know why it went dead. I put it on a charger and it took a full charge according to the charger.
When Son drove it home from the park he says that the check engine light was now on at that point. Sienna seemed to drive OK coming home and for a next 12 mile round trip. Now I pulled the codes today and there are 2 of them as follows: First Code: PO155 Mod$10 O2 sensor Heater Circuit Malfunction Bank 2 sensor 1 Second code: PO155pd Mod$10 O2 sensor Heater Circuit Malfunction Bank 2 sensor 1 (same as first code but with that additional pd)
Then I pulled the "Freeze Data" (if this helps) Engine RPM 1508 Calc Load % 14.1 Coolant deg F 185 IATdeg F 95 LT FTRM1(%) 0.0 ST FTRM1(%) 5.5 LT FTRM2(%) 5.5 ST FTRM2(%) 3.1 Veh speed (mph) 45 Fuel sys 1: CLSD Fuel sys 2: CLSD
OK so here are my questions (If I should be posing other questions let me know):
1) What exactly do I need to do about this? 2) Is it easy enough for me (I am reasonably adept, but not a superstar)? 3) Can I go on the trip without doing it and what would be the consequences?I have one afternoon to do it - tomorrow. Thanks for this help folks. Tomes
