- 97 Mounty 5.0
I need some help diagnosing a problem. I am short on time, so tracing wires and hunting for diagrams would be slow going. So, I am throwing it out to the community in the hopes that someone can help identify the issue.
BACKROUND: 97 mounty I just put a 347 into. I used a rebuilt 4r70w trans from a 98 and found out when plugging in the trans wiring harness (which has 3 of the 4 O2 sensors), that the shift lever sensor doesn't plug in. I bought a new one for a 97 and got a 98? same item showed up on every site, but found the right one from a 96 F150. then found out in my searching, that the internal electrical stiff is different too. I found a diagram to repin the internal trans connector to work with the 98 trans and performed the repin job. it wasn't too difficult. I did end up with 2 or 3 (can't remember off hand) extra power wires that weren't being used with the 98 trans, so I just pinned them to the non-used spots in the connector to keep it clean.
WHATS HAPPENING: ok, so the engine starts and runs. I took it for a slow drive around the block and all gears shift perfectly, so I am certain I did the repin correctly. but its got no power and stumbles with the slightest touch of the gas and I have a slew of codes.
P0135 (o2 heater b1,s1)
P0141 (o2 heater b1, s2)
P0155 (o2 heater b2, s1)
P0161 (o2 heater b2, s2)
P0171 (system too lean)
P0453 (evap press high)
P1000(system readiness not complete)
From reading, the O2 heater issues may be the main problem with power. heaters inop will cause improper readings and the PCM will adjust the fuel tables to compensate.
I looked for a blown fuse that may be related to the heaters, but all fuses are in good working order. I didn't modify any of the O2 sensor wiring in the trans harness, so unless one of the extra power wires that were not needed for the trans controls was somehow supposed to power the heaters, it should work, right?
any suggestions? like I said, I have very little time these days, so I am hoping to avoid tracing wires. if someone can tell me what pins to check and for what, it would really help a lot.
