TPS not registering when car running, WTH?

Post by kredden »

In the tuning phase with my MS-II now and have an odd one. When the ignition is on run but the car is not running (i.e. power going to MS but engine not running) my Volvo 850 TPS reads fine in MegaTune, when I step on the throttle the TPS % rises as expected and drops when I let off. So far so good.

After I start the engine the TPS % no longer registers in MegaTune. For my pigtail harness between the L-Jet connector and the MS-DB37 I've got the following:

LJet 2 -> MS 26
LJet 3 -> MS 22
LJet 18 -> GND

Do I have one of the wires switched or something? Not sure why the engine running would make a difference.

Thanks,
Kevin

Swapped the TPS for a spare and it works now, weird! Good thing I thought to pick up two at the junkyard...
