DTC P0201/P0262 THROTTLE BODY FUEL INJECTOR FAULT
Circuit Description
The ECM controls the fuel injector by grounding the
control circuit via a solid state device called a driver. If the
ECM detects an unacceptable difference in resistance, a
fuel injector control DTC is set.
Although the DTC indicates that the fuel injector is faulty,
the technician must determine if the fault is in the ground
circuit, the +12v circuit, or in the fuel injector.
NOTE: If an ignition coil fault code is active, the fuel
injector will not inject fuel to the cylinder with the faulty
ignition coil.
Diagnostic Aids
Check for the following conditions:
1. Poor ECM connection.
2. Inspect wire harness connectors for backed out
terminals, improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal to
wire connection.
3. Damaged wire harness and/or connectors. If harness
appears to be OK, shake or wiggle wire harness
and/or connector with DVOM attached. Radical
voltage changes can indicate the location of the fault
condition.
Always clear DTCs after performing repairs.
