The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Candidate cause (the documents say what to do)

Reduced Engine Power from throttle body connector crimp, broken wire or grounds

A vehicle may come in for a reduced power message and DTCs P0120, P0220, P1516, P2101 or P2135.

The TAC / throttle body codes may be caused by a loose wiring crimp at the throttle body connector or a broken throttle body circuit.

How to tell

P0120P0220P1516P2101P2135Check engine / Service Engine SoonReduced Engine Power

What to do

  1. Inspect all related throttle body terminals for a loose wiring crimp.
  2. Wire breaks usually occur within 1 to 4 inches (= 25.4–101.6 mm) of the throttle body connector.
  3. On C/K trucks, complete SI procedures for voltage drop on grounds G103 and G104; grounds G103 or G104 may be loose or corroded.
  4. If a terminal crimp or broken wire is found, repair or replace only the circuits involved.

Caution: Installing this pigtail connector may cause other intermittent TAC module / TP codes at a later date.

A cause or a result a complaint states is the owner’s view or what a dealer told them, not an established fact.

Put together by FaultCrate from public records and technical documents. The cause and the repair are for the workshop to decide with the vehicle in front of it. Counts are records, not failure rates.
