Question about 2003 Ford Explorer Sport
I understand about the MAF and other solutions posted related to emissions and cold weather but my problem is different. I have a 1999 Ford explorer, currently 82,000 miles whose transmission was rebuilt at 61,000 miles. The trouble when driving is that the automatic shifting is not consistent and the car revs up high before getting into the right gear. Could this be related to the PO 171 and Po 174 codes or something else. Thank you in advance.
Transmision shifts are based on engine load imputs a 171 and 174 refer to a lean condition therefor the shift is being based on an assumed cold engine so yes it may be related

CHECK YOUR TRANS OIL SEE IF IT LOOKS BURN AD SMELLD BAD YOU CAN MANUAL SHIFT YOUR TRANS AND YOU WILL SEE THE PROBLEM IS IN THE TRANS . TEST DRIVE BUT DRIVE IT SLOW WITH NOT A HEAVE LOAD AND IT WILL STILL SLIP. KEEP IN MIND WHEN ANY THING THAT FAILS IN THE FUEL INJECTION . IT WILL HURT EMISSION AND PERFORMANCE BUT WILL FAIL SAFE. THAT MEAN THE CAR WILL STILL RUN. WORK ON THE CODE AND THE FIX THE TRANSMISSION.

SOURCE: error codes po 134 po
PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS
