Loosing TPS signal when engine startup.

Post by snerky »

Hi,

I have a problem i can't figure out of.
I have a Civic Ej2 95 with a B20vtec with a newly mounted Rywire engine harness.

After installing the harness im having problem with the TPS sensor signal cutting when starting up the engine.

Im having the tps signal showing on the Smanager display 0-100%. But when im starting up the engine. The display only showing 0%.

And the car is now not possible to drive due to not possible to handle in the mid specter of the pedal. Only small movement on pedal or pedal to the metal (Fully open throttle)

What could this be?

Thanks!

I would suggest you try going back to the stock harness and see if that works properly. If it does then you know you have a bad harness.

Hehe, i was waiting for this suggestions!
The reason i havent is because the connectors on the old harness were cut away by my tuner... so its not the easiest thing to fix.

But i have ohmed the tps connector to earth. And the connectors and connectiom looks good.

I have also replaced the tps sensor and calibrated it. And same thing happens when engine starts up.
