16* Knock sensor either shorted to ground or 12 volts. Will not detect open circuit
uh huh how the hell can this happen?


32** Open or shorted condtion detected in the EGR transucer solenoid circuit
and this is ?

Code 32, is a fault with the EGR transducer. Here's some info on it:



The electronic EGR transducer contains an electrically operated solenoid and a back-pressure transducer. The Powertrain Control Module (PCM) operates the solenoid. The PCM determines when to energize the solenoid. Exhaust system backpressure controls the transducer.



When the PCM grounds the solenoid, which causes it to energize, vacuum does not reach the transducer. Vacuum flows to the transducer when the PCM de-energizes the solenoid.



When the exhaust system backpressure becomes high enough, it fully closes a bleed valve in the transducer. When the PCM de-energizes the solenoid and backpressure closes the transducer bleed valve, vacuum flows through the transducer to operate the EGR valve.



De-energizing the solenoid, but not fully closing the transducer bleed hole (because of low backpressure), varies the strength of vacuum applied to the EGR valve. Varying the strength of the vacuum changes the amount of EGR supplied to the engine. This provides the correct amount of exhaust gas recirculation for different operating conditions.





Transducer Assembly-3.5 engine



I would check the wireing and hoses going to the transducer assembly. Maybe some didn't get put back on right.
