• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

got some trouble codes

P0332 Knock sensor 2 signal short/low
&
P1811 Maximum adapt & long shift

Soo i'm guessing the knock sensor needs to b replaced but the other code has to do with my tranny, i looked it up and it says something about it not shifting fast enough or something, idk if this has to do with my tep tranny or my zzp pcm???
 


The PCM contains integrated Knock Sensor (KS) Diagnostic Circuitry. Input signals from the knock sensors are used to detect engine detonation, allowing the PCM to retard Ignition Control (IC) spark timing based on the amplitude and frequency of the KS signal being received. The knock sensors produce an AC signal under all engine operating conditions. The PCM calculates an average voltage of each knock sensor's signal and takes instantaneous signal voltage readings. The PCM uses the instantaneous signal voltage readings to determine the state of the knock sensor circuitry. If the knock sensor system is operating normally, the PCM should monitor instantaneous KS signal voltage readings varying outside a voltage range above and below the calculated average voltage. If PCM detects a Knock Sensor 2 signal voltage within the calculated average voltage range, DTC P0332 will set. Refer to Knock Sensor (KS) System Description for further information.it says you shouldCheck for the following conditions:
• Poor connection at the PCM or Knock Sensor 2.
Inspect knock sensor 2 and PCM connectors for backed out terminals, broken locks, and improperly formed or damaged terminals.
• Misrouted harness.
Inspect the knock sensor harness to ensure that it is not routed too close to high voltage wires such as spark plug leads.
 
and your other code.The transmission pressure is modified by an adaptive modifier which controls the shift execution time. This test checks the time required to accomplish the shift. If the shift takes longer than 0.65 seconds, and the adaptive modifier cannot shorten this time, then a counter increases by one.

If the PCM detects the counter reaching two, then DTC P1811 sets. DTC P1811 is a type D DTC., and for this there is a tsb to replace the pressure control solenoid, part number 10478146, i hope this helps
