can someone tell me what code this is p-0326 on 04rxp???

i have my sheet in front of me and i dont see a p0326 listed as a code are you sure about the number they show a 236 knock sensor..and a 336 crank sensor wrong rpm

P0326 — —
Knock sensor out of range
Damaged sensor, damaged circuit wires, damaged connector or damaged ECM output pins.
Bring engine to 5000 RPM. If fault code appears then check for approximately 5 Mohms between system circuits A-9 and A-23.

Fault is detected by system while running, so the electronics have not picked up a fixed/wiring fault as a rule.
Usually slack engine internals or ECM is set for too low a threshold.
Or.... the dreaded "pig-tail" problem.

he said the code was 326 that code isntshown on my sheet..236 is..knock sensor

Here's the procedure for an '03 SC. It might help:
Using the vehicle communication kit (VCK) with the B.U.D.S. software, monitor the knock sensor using the Faults section.
Start the engine and bring engine RPM above
5000 RPM. If no fault code occurs, the knock sensor is good. Otherwise, do the following.
Ensure sensor and cylinder head contact surfaces are clean and mounting bolt and washer are correct and properly torqued down.
NOTE: It is necessary to remove intake manifold to inspect contact surfaces. Refer to INTAKE SYSTEM section.
Check the knock sensor resistance:
Disconnect the connector from knock sensor harness. Static Resistance Test Using a multimeter, check the resistance between
both terminals on the knock sensor harness side. The resistance should be approximately 5 MΩ. If resistance is not good, replace knock sensor. If resistance is good, reconnect the knock sensor connector and disconnect the EMS ECU connector A from the EMS ECU. Using a multimeter, recheck resistance value between terminals 9 and 23.
If wiring harness is good, try a new EMS ECU. Refer to EMS ECU REPLACEMENT procedures elsewhere in this section. Otherwise, repair the connector or replace the wiring harness between EMS ECU connector and knock sensor.
Remove the intake manifold. Refer to INTAKE
MANIFOLD REPLACEMENT in INTAKE section.
Unscrew and remove knock sensor. Clean contact surface, apply Loctite 243 in threaded hole then install the new knock sensor. Torque screw to 24 N•m (18 lbf•ft).
CAUTION: Improper torque might prevent sensor
to work properly and lead engine to severe
damage of internal components. Replug connector.
....I got this from google, hope it helps.

Thanks everyone got it sorted.. The pig tail was faulty all of a sudden... Do they fail sometimes??

I got the same fault in an 06, will check as per above.

Dreaded Pigtail? Did i miss a thread somewhere or what?
