WR250f TPS Fails Sporadically

Recommended Posts

Greetings,

Purchased a new 2016 WR250f. Check engine light comes on intermittently about every 35 miles (fault code 16 TPS failure) at which point the idle speed and rpms significantly increase, then subsequently decrease, oscillating about every 10 seconds between high and low rpms, followed by a little smoke and sputter out of exhaust. Anyone experience this? I have about 130 miles on this machine, and it's all stock. I've had all sensors, and electrical components inspected, including TPS, and all is in spec. Thanks.

You need to test the components whilst replicating the fault. Back probing with a graphing scope/meter is the easiest way. Measure the loom and check your connectors whilst your at it.
