Help with code p1121

[Boads]

Hey everyone, so I have done my research and used the search to find as much info as I could but it seems I can’t find a solution to my exact issue . So I have had my 2001 4runner for a little over a year. Occasionally I would lose power to the pedal and have to press all the way down pedal to floor to get the car to go again . This happened only a couple times and never threw a code. The second I restarted the car it was back to normal . Now it has been happening more often and this time it’s throwing the code p1121 (accelerator pedal position sensor range / performance problem) . I replaced the TPS with a brand new one and the problem persists . So I’m assuming it is the APPS and not the TPS. But I also noticed that the plastic coating around the accelerator cable is starting to come off the wire . So before I go and buy an entire throttle body assembly ( because as far as I know there is no direct part for the APPS) I am wondering if the aging of the cable could cause the problem? Ill attached a picture .

Basically I don’t want to buy a throttle body have the problem persist after spending all that money because I don’t believe the throttle body comes with a throttle cable replacement

Also forgot to mention the problem seems to happen far more often in the cold weather . And it may sound strange but I seem to notice the loss of power happens sometimes went I am going over a bump in the road like a speed bump or a quick dip in the road Way, but it’s not limited to that

Bump. Have this issue just today. What’s the fix for this. Please help. Check engine light is on as well.

Checked the FSM, only one thing to do, replace the accelerator pedal position sensor. OEM: 89452-35020, about $80.

Did the replacement work?
