Claim 0:
1. An intake air heating system for a vehicle, the system comprising:
an air heater configured to heat air in an intake system of an engine;
an air heater control module configured to selectively apply power to the air heater via a power conductor; and
a voltage sensor and communication module configured to:
measure a voltage on terminals of the air heater; and
transmit an indicator of the voltage to the air heater control module on the power conductor,

wherein the air heater control module is further configured to:
receive the indicator via the power conductor;
determine a resistance of the air heater based on the voltage on the terminals of the air heater and a current through the air heater; and
apply power to the air heater based on the resistance of the air heater.
