cel Code 7
d4 flashes code 4. ....with original ecu...tach good
Im checking my TPS or trying too, Should i have 5v at the TPS with the gas pedal no depressed? Its got tree wires,
Between Battery grnd and the YELLOW wire i get 5v...NO THROTTLE
Between GRN (With Black probe) and the other probe on the RED wire i get .5v with NO THROTTLE
Between GREEN AND YELLOW I get 5v....NO THROTTLE
Between Battery grnd and the Red wire I get 4.15v @ WOT
Between Battery grnd and the YELLOW wire I get 5v at @ WOT
Between GREEN (With Black probe) and YELLOW I get 5v At@The WOT

For the TPS:
Terminal no. 1 - Grn/Blu wire is sensor ground from ECM
Terminal no. 2 - Red/Blk wire is the TPS inputs to ECM and TCM
Terminal no. 3 - Yel/Blu wire is reference voltage from ECM (should be 5 volts)
Closed throttle (accelerator not depressed):
Terminal no. 2 - Red/Blk wire should be approx. 0.5 volts.
Wide Open Throttle (WOT):
Terminal no. 2 - Red/Blk wire should be approx. 4.5 volts.

Your TPS may be okay. I am wondering whether you have a short on the ECM sensor ground wire.
Looking at the circuit diagrams, the ECM provides sensor ground on the Grn/Blu wire to the following components:
Try this:
With the TPS unplugged, with the voltmeter's black lead on the Grn/Blu wire connector cavity terminal, check to see whether you get a voltage reading on when you touch the voltmeter's red lead to the Yel/Blu wire cavity terminal; with the ignition ON.
If you don't get a voltage reading doing that, you may have a short in the Grn/Blu wire.

- Throttle Position Sensor
- EGR valve lift sensor
- Engine Coolant Temperature (ECT) sensor
- Front Heated O2 sensor
- Intake Air Temperature sensor

Do the test at the TPS connector, between Grn/Blu wire connector cavity terminal and the Yel/Blu wire cavity terminal; with the ignition ON.
Do not jump the service check connector while you do this.
