Question about 2004 Dodge Neon

1 Answer

Engine code suggests Knock sensor is bad...but where is it at?

I have the following 2 codes on a 2003 dodge neon.
Knock Sensor 1 circuit malfunction (bank 1 or single sensor)
Evaporative Emission Control System Incorrect Purge Flow

How do I locate the knock senor 1 and is it easy to replace. I've had the EECSIPF code in the past and it is usually the gas cap not being tight enough. Please let me know if you know where this sensor is located and if an average do it yourself-er can get it done in his garage or if it is easier to just bite the bullet and take it in.

Thanks!

    P0325 is the code in question

    The other code is P0441

    Any idea what it might be if it's not the knock sensor?

    i would need to have a full diagnostic run and then read the data from a road test to determine cause, have replaced zero knock sensors in 20 years.

Knock sensor is on the block, easy to do. not sure exactly where it is on your specific car but it looks like a fat bolt with 2 wires running out of it. but also check the wiring if its good for the knock sensor

I have a PT 2010 & the diagnostic codes are PO340, PO344 and PO325. mechanic is suggesting replacing the cam shaft post sensor & didn't even mention the knock sensor. Am I dealing with 1 or 2 issues


you are dealing with 2 issues
code p 0325 refers to knock sensor (KS) 1 bank 1--circuit malfunction ====causes ---wiring ---poor connection ---KS
code p 0340 refers to camshaft position sensor(CMP) sensor A bank 1--circuit malfunction===causes wiring--- CMP sensor ---ECM
code p 0344 refers to CMP sensor A bank 1 --circuit intermittent===causes --wiring --poor connection---CMP sensor --ECM
check wiring and connections before replacing the CMP as the wiring may be the cause of all the codes

Why is error code p0327


Code P0327 indicates that the readings from the #1 Knock Sensor circuit are too low, is outside of its operational window and malfunctioning. Symptoms
  • Check Engine Light will illuminate
  • Engine pings on accelration
  • Engine may be running hotter or colder than normal
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0327 Code
  • Defective Knock Sensor
  • Defective Knock Sensor Circuit or connections
  • Defective EGR System
  • Malfunctioning Cooling System
  • Rich air/fuel ratio
Common Misdiagnosis
  • Knock Sensor replaced when cause of code P0327 was a cooling system problem
  • Knock Sensor replaced when cause of code P0327 was an EGR system malfunction
