code p0122 but test fine

[occamaroz]

I keep throwing this code with 2 different tps sensors. I check the plug and it fine with 5.0 volts key on. Then I backed probed the tps and opened the throttle slowly and get 4.6 volts with no dead spots. The car has been running very low on power with a rough idle. Also I got a unknown code 1122.

1122 is another tps code for an intermittent excessively high voltage

sounds like it's intermittent which is why you're meter is showing good when you test it.

Code 1122 Is "TPS pedal position Intermitent, Low voltage"

The Throttle Position (TP) sensor is used by the PCM to determine the throttle plate angle for various engine management systems. The TP sensor is a potentiometer type sensor with 3 circuits, a 5-volt reference circuit, low reference circuit, and signal circuit. Rotation of the TP sensor from the closed throttle position to the Wide Open Throttle (WOT) position provides the PCM with a signal voltage from less than 1 volt to more than 4 volts through the TP sensor signal circuit. If the PCM detects an intermittent, excessively high signal voltage, this DTC will set.
Check your harness again and ensure all the pins are clean, dry and dont shift around. Also check for bare wires that could be causing a short.
