P1300 on Toyota: Causes, Symptoms and Fix Cost

Quick Answer

Not safe to drive

P1300 on a Toyota is a manufacturer-specific code. Toyota and Lexus define it as igniter circuit No. 1: the engine computer sends an ignition timing signal (IGT) and does not get the confirmation signal (IGF) back from the igniter. Ford lists it as a boost calibration fault, a turbo boost pressure fault that is usually traced to the boost pressure sensor or its wiring, and Honda, Audi and Volkswagen list it as a random misfire. The repair steps below cover the Toyota and Lexus meaning only. It is not the same as P0300, which is a random misfire code on every make.

What does P1300 mean on a Toyota?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Toyota models that log P1300.

Toyota Tacoma 2.7 (1996)

1996

Motor magazine describes the Toyota P1300 logic: the code sets when the engine computer sees correct camshaft and crankshaft signals and a good IGT but receives no IGF, and the computer stops fuel injection as a fail-safe when IGF is missing. In its case, a 1996 Tacoma 4x4 with the 2.7-litre engine cranked but would not start with P1300 stored. The author suspected a voltage drop in the ignition circuit, and the truck ran again after the distributor cap and rotor were refitted, though the author doubted the fix was permanent.

What causes P1300 on a Toyota?

Beyond the generic causes listed on the main P1300 page, these are the patterns noted for Toyota models:

  • Voltage drop or poor connection in the ignition primary circuit

  • Distributor cap and rotor

How to diagnose P1300 on a Toyota with OBD2

  1. Confirm the car is a Toyota or Lexus. On a Ford the same number is a boost calibration fault, where the boost pressure sensor and its wiring are the first place to look, and parts bought for the wrong definition will not help
  2. Read all codes. P1300 is the number 1 igniter circuit, so look for codes for other igniter circuits stored with it: several together suggest a shared fault such as power or ground, one alone points at that coil and its wiring
  3. Inspect the coil and igniter connectors for broken wires, loose pins and corrosion, and look for harness damage near the valve cover or where the intake has been removed
  4. Check power and ground at the coil and igniter. Poor grounds and power-side problems are among the most common causes
  5. Check that the crankshaft position sensor is giving a signal, since the igniter gets no trigger without it
  6. Check the IGT trigger and IGF return signals with a scope or test light. A generic reader cannot show these signals, so this step needs a workshop or a proper tester
  7. Replace the igniter or coil only after wiring, power and ground are proven good, then clear the code and road test
