I have a 1987 Mustang GT converted to MAF and the TPS sensor went dead.
No part number and looks like a cheap Tru-Tech part.

I would like a Motorcraft part but they have 2 part numbers cx1133 or cx1323

Which one is which?

Thanks!

 

Either one will work OK, CX 1133 would have been original on the 87. When I converted my 87 to MAF, all of the original sensors were still there, so that won't cause an issue. Visually the CX 1133 and CX 1323 are identical.

thank you, I appreciate it. Ford had no idea!
I went ahead an ordered CX1133

 

The CX 1323 didn't actually start until 1989 model year (1988 in Cali), but I don't know why a Ford dealer would mention both for a 1987. When I look in the computer catalogue and the printed Motorcraft catalogue, it only shows the CX 1133 for a 1987 Mustang.

Put new one in and darn signal wire (Green) is at 5 volts still... So did a manual gorund to the TPS and it works.
GREAT!! might be fried signal wire to the the PCM or bad ground. Time to to do electrical, we know how everyone loves electrical!
