Hi, my name is ***** ***** you pulled codes from the computer yet?

Customer: replied 11 months ago.
No I haven't.
Expert:  Tim Mohr replied 11 months ago.

this can be either a bad lift pump or injection pump, codes will help determne this, can you have the codes read?

Customer: replied 11 months ago.
I will do that right away. Shouldn't take more than an hour.
Expert:  Tim Mohr replied 11 months ago.

let me know,Tim

Expert:  Tim Mohr replied 11 months ago.

I will be off in about a half hour, but will return in 2 hours,Tim

Customer: replied 11 months ago.
Okay. I know there's some fuel pressure at the injecton pump but not sure how much. It looks like I may be replacing both for a better performing system but I will check for codes.

let me know the codes

Customer: replied 11 months ago.
Okay, two codes. P 0234 and P 1693
Customer: replied 11 months ago.
Sorry not P 0234 it was P 0236 and P1693
Expert:  Tim Mohr replied 11 months ago.

are you sure it wasnt a a P0216 and a P1693?

Customer: replied 11 months ago.
I'm very sure it was P 0236 not P 0216.
Customer: replied 11 months ago.
It said it was a supercharger/ booster sensor A circuit.....
Customer: replied 11 months ago.
P0236 Turbocharger/Booster sensor A circuit range/performance
Customer: replied 11 months ago.
a P1693 that said a DTC was stored in the ECM and the PCM.
Expert:  Tim Mohr replied 11 months ago.

THE p0236 WILL NOT CAUSE A NO START, BUT THE 1693 CAN, DEPENDING ON WHAT CODE IS STORED IN THE ECM, ecm CODES?

Customer: replied 11 months ago.
Would the "check engine" light be on if there were codes stored in the ecm? Because the check engine light never came on and still is not on. And can I get the DTC's by cycling the key on and off three times?
Expert:  Tim Mohr replied 11 months ago.

Not neccesarily, it may alays come on, but the P01693 means there is a code stored in one of the other modules, either the transmission module, or the engine control module, the key trick only reads the PCM codes, so you will need a scanner or a code reader that reads other modules,Tim
