Code p0328 and P0171 nissan - Xterra Nissan Cars & Trucks

Run an OBD code scanner or lookup what the code means. Don't always rely on the codes though.. they can be a red herring.

The service manual usually has information on the codes http://onlyrepairmanuals.com/downloads/nissan-pathfinder-repair-manual-1995-2005/

Here's code P0442. P0442 OBD II Trouble Code here's code p0328 P0328 Knock Sensor Circuit High Input

code p0733 refers to gear 3 -incorrect ration===causes---wiring---TR sensor/switch--shift solenoids---transmission mechanical fault
code p0420 refers to catalytic converter system -bank 1---efficiency below threshold===causes--cat converter--wiring--HO2s 2
code po430 refers to cat converter system bank 2--efficiency below threshold===causes--cat converter--wiring ---HO2s 2
code p0328 refers to knock sensor (KS) 1 bank 1--high input===causes--wiring short to positive--KS incorrectly tightened--KS---ECM

basically replace the cat converters as they are blocking the exhaust system and preventing your over 45mph problem
replace the TR sensor/ switch as you have not mentioned a transmission problem
Rectify the problem with the KS as it controls the air/fuel mixture setting which contributes to the car getting hot.

Hi Candy,here's a link to the P0171 code.Here's the code P0325. O n the Code P0171.it says it will have a

• detonation (spark knock) which,the first code is causing the second code to go off.

Code 328 is for the knock sensor which is a common code for Nissan products. it does not always mean the sensor has failed.
Code 462 usually means the computer is not getting a signal from the sending unit in the gas tank. Have you checked the signal at the tank harness ?

A quick search indicates P0328 is a knock sensor high input code, so I would start with that.

P0328 Is knock sensor code,all Nissan have this code so leave,concentrate on P0101 and P0103 this is MAF(mass airflow),Just make sure the timing belt is in good condition and the marks are correct, your solution is NTB02-003A In other word you need a reprogram on the ECM
