Sorry I have taken so long to respond but I had a death in the family. Installed 2 throttle bodies and car ran fine for 3 days then did the same thing but worse. DTC P2166, DTC P2167. I am going to try to get another scan tool because whenever I try to access throttle parameters I get the message P2166 ACCELERATOR PEDAL POSITION SENSOR 1 MAXIMUM STOP PERFORMANCE.(operation has been stopped due to the following reasons. 1. Vehicle Condition is out of test condition.
2. No response from vehicle ECU. Refer to service manual, confirm
test condition & vehicle condition.
P2167 ACCELERATOR PEDAL POSITION SENSOR 2 MAXIMUM STOP PERFORMANCE and I get the same message as above.
The research I have done so far keeps pointing toward the accelerator pedal potentiometer is not working. I am trying to get to it to check it with a volt ohm meter but in order to remove it you have to completely remove the brake, clutch pedal and throttle as a unit and it is only sold as a complete unit. A lot of labor to remove it.That makes a gas pedal cost over $4000.00 not including labor. This is my second Viper. The only modifications, are high flow cats, Belanger
exhaust, and Gen 5 intake. Any help would be very much appreciated.
Thank you.
