Trouble code dtc 332

[Skyhigh351]

So on my 92 bronco 351 I finaly got the check engine light to come on so I can figure out why my truck is sputtering and not having enough power, the code came up dtc 332 insoficent egr flow, don't know what the heck it means, I have a new egr valve on, but with the old sensor on it, I checked for clogs it was all clean, what should I do to fix this ????

I'm desperet haha it's not funny tho

yo, it happens...

If you have a Haynes Manual go thru the pin-point tests; if not, here is some info for you.

332 - Insufficient EGR flow detected; "Atop the EGR valve there is a sensor called the EVP (EGR Valve Position) sensor. It detects movement of the pintle iside the EGR valve. You can apply vacuum to the vacuum barb on the EGR valve and observe through the holes in the casting whether the valve is moving or not. It may just be dirty which requires some careful scrubbing and NO SOLVENTS. Otherwise, if the EGR valve is functioning and moving when vacuum is applied, the EVP sensor is suspect and the electrical connections to it should be checked first. (Computer needs to know the EGR valve position for emissions control)."

Testing; "...Using the Haynes manual's procedures, you should be able to back-probe the EVP line and ascertain whether the EVP voltage is correct. It should be below 0.67V @ zero vacuum on the EGR, slowly increasing with applied vacuum from a hand pump. DO NOT apply more than 10 in-Hg to the valve..."

We have run into many situations where

a code for insufficient flow has been set and the

system is functioning correctly. Then it is time

to check the EGR passages. There is a Ford

Technical Service Bulletin (TSB 96-23-4) that

addresses this for some vehicles. This TSB

includes:

1992-1995 Crown Victoria

1994-1995 Thunderbird

1991-1995 Town Car

1992-1995 Grand Marquis

1994-1995 Cougar

DTC 332, P1407 and P1408 or detonation; "...We have run into many situations where a code for insufficient flow has been set and the system is functioning correctly.

If exercising the EGR valve does not result in a change in rpm, then the passages may be clogged. There are
