LQ9 Throttle Blade not opening fully DBW more info
Ive gone through other posts having somewhat similar issues and not found an answer to my issue. So I decided to do some hard number measurements.
Throttle body connector values. 8 Pin , volts
Terminal Key on Idle (engine off) Key on Throttle Full (engine off)
A 1.6 11.56
B 0.4 0.33
C 1.6 10.31
D 0.3 0.39
E 4.27 4.3
F 1.0 2.00
G 1.1 2.38
H 4.9 4.9
To me the issue is clear, F & G are not getting full voltage. Those are the TP Sensors.
Rehashing. The swap was from a 2004 Escalade into a 96 Impala. Full Pull , ECM, Pedal and TAC, that started out OK, 400 Hp at RW.
Driveability issues at low speed , the Tuner made several adjustments. Some Improvement. Thats when I noticed the issue with throttle not opening fully.
I replaced pedal sensor, TAC, and swapped TB. No Change.
Now I ran across a post where a tuner used a 2005 Tune in a older ECM. Im assuming my ecm is E40 ? and had similar issues.
What do i need to do to figure this out ?
No Codes are showing except MIL, supposedly turned off as no lamp is lit.
