Got code 12 exhaust gas recirculation temperature sensor. Or Absolute pressure valves from ELZ ignition control unit
Those 2 descriptions are from 2 different code lists.
I cleaned my egr and cleaned the tube. It was clogged but sprayed lot of carb cleaner and air in there and finally the air went into the intake. took for a test drive still got the light but it took longer to turn on.
Were is this sensor
pls help I need to smog the car.

Its a 91 300te 4 matic ca edition with blinker for code reader 3.0 engine

Code listed is for the 2nd problem.

Look for broken vacuun line at the EZL.

What is the ezl? I was guessing it was those 2 vaccume sensors thats pluggerd in on the left inner fender.
ty for reply

EZL = ignition control module located on left inner fender.

Might be a dumb question. do u mean the left side driver or passanger. I look at the engine compartment left side (passanger)

Are you talking about the driver side were the coil is? Its got 2 sccrew things on it and vacuum line going to it?:)

Heres the passanger side engine would those cause an issue? will the blue things go bad (check valve?)

Is it true at 2000rpm all those sensors open and all should have vacuum. Theres vaccum to red (from engine) Not from other side. Theres also vacuum on blue. (one line with elbow)
