Question about 2001 Nissan Frontier Crew Cab
HI. This will be a straight forward approach here. The knock sensor code is in reference to the sensor voltage. This sensor will need to be replaced. I would also advise to inspect the connecting harness connectors for faults. The harness links the sensor to the ECM. Make sure that harness is not shorted by testing it with a meter. You can test the sensor by Starting the engine and run at idle. Next; Measure voltage at the ECM pin 64. The voltage should be approximately 2.4 vDC.
Now; the TPS code is a basic failure code. You will simply need to replace that sensor. That sensor has failed, or it is damaged, thus, causing the erratic shifting patterns you are experiencing at this time.
Concerning your distributor:
This device should not rattle. There my be a looses ring strop connector, or the internal components may be deteriorating. I would inspect the cap mounting and internals for faults. Replace the entire distributor if faults exist.
