Diagnostic Aids

WARNING: This page is about a different car, the 2003 Lexus GX 470. However, it is still accessible from the selected car via links, so may be relevant.
  1. After confirming DTCs P0110, P0112 and P0113, use scan tool to access CURRENT DATA to confirm air intake temperature. If temperature displayed on scan tool is -40°F (-40°C), IAT sensor circuit may be open. If temperature displayed on scan tool is 284°F (140°C) or more, IAT sensor circuit may be shorted.
  2. If DTCs P0110 and P0115 are output simultaneously, ECM terminal E2 (sensor ground) may be open. See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
  3. Read freeze frame data using hand-held tester or OBD-II scan tool, as freeze frame data records engine conditions when a malfunction is detected. When troubleshooting, this is useful for determining whether vehicle was running or stopped, engine was warmed up or not, or air-fuel ratio was lean or rich at time of malfunction.
