What does P0267 mean?
SAE J2012 APR2002 names P0267 Cylinder 3 Injector Circuit Low. Circuit low is measured with the injector connected. P0268 is cylinder 3 circuit high. The two service charts below do not agree on what an open does, so the chart has to match the vehicle.
On the 2009 G3 7.5–16 V Type A procedure in AllOEMManuals G3 L4-1.6L and gm.saturn.team 7725/145178, P0267 sets when the ECM detects injector 3's control circuit open or shorted to ground. A short to voltage on that procedure is P0268. Enable is the engine running and ignition 1 voltage between 7.5 and 16 volts. That procedure calls the set Type A and commands open-loop fuel. Terminal 1 is ignition and terminal 2 is control. Document 8100/175665 prints 11–16 volts, Type B, and swaps those terminals, so the pins below are not every 2009 G3 connector. The feed lamp comes first: ignition off, unplug the injector, ignition on, terminal 1 to ground must light. No light repairs the ignition feed for a short to ground or an open/high resistance, fuse included. That is not yet a control-wire conclusion. J 34730-405 between control terminal 2 and ignition terminal 1 should flash with the engine running. Always on: short to ground on the control wire, and the ECM only after that wire tests normal. Always off: the chart's shared sentence says short to voltage or open, while P0267's own setting line is the open or the short to ground. Write the result you measured. Resistance is 11–14 ohms from terminal 1 to terminal 2 at 10–32°C (50–90°F).
On the 2008 Pontiac G8 3.6L page the split is different. P0267 sets only when the control circuit is shorted to ground for greater than 4 seconds or for a cumulative of 30 seconds. The open is P0203, for greater than 4 seconds or a cumulative of 30 seconds. A short to voltage is P0268. Enable there is engine speed greater than 80 rpm, ignition voltage between 10 and 18 volts, and the injector commanded on and off at least once. The control circuits are pulled up inside the ECM. Disconnecting the multi-way sets P0201–P0206, which the procedure says to expect. A test lamp from the control pin on the ECM side of that multi-way to B+ should stay dark. If it lights, test the control wire for a short to ground, and replace the ECM only if the wire is normal. The 2.6–4.6 volt check is the next step, and a miss there is an open/high-resistance test, not an instant short. Coil resistance on that page is 12–16 ohms, with no temperature window printed.
A third chart, the 2007 LY7 low-voltage procedure, groups P0261 with P0267 and P0273 when one bank's ignition feed is shorted to ground. One P0267 alone on that chart goes to the single control wire. Three together go to the shared feed. Do not move that bank rule onto a G3, which has no cylinder 5.
Common causes
- On the 7.5–16 V Type A G3 procedure, injector 3's control circuit open or shorted to ground
- On the 2008 G8, injector 3's control circuit shorted to ground for greater than 4 seconds or a cumulative of 30 seconds
- On the 2007 LY7 chart, the shared bank ignition feed shorted to ground
- The ECM driver, after the control wire on that chart tests normal
Symptoms
- P0267 stored
- Open-loop fuel on the G3 Type A set
- A test lamp that will not light at G3 terminal 1
- A test lamp from the G8 control pin to B+ that lights, which is the short-to-ground branch
- P0203 stored on a G8 if the circuit is open instead
- P0261 and P0273 stored with it on the LY7 bank-feed row
Diagnostic steps
- 1.Read which chart the vehicle uses before unplugging anything. The G3 low code includes an open. The G8 low code does not. The open there is P0203.
- 2.On the 7.5–16 V Type A procedure: ignition off, unplug injector 3. Ignition on. Lamp from ignition terminal 1 to ground. No light: feed short to ground or feed open, fuse if it opened. A dark lamp there is the feed, not the control-wire fault that sets this code.
- 3.On that procedure, J 34730-405 from control terminal 2 to ignition terminal 1, engine running, should flash. Stay off the belt and the fan. Always on: short-to-ground test, ECM only if the wire is normal. Always off: short to voltage or open, as two results. P0267's setting line is the open or the short to ground. The G8 files an open as P0203, and both charts file a short to voltage as P0268.
- 4.On that Type A procedure, ohms are 11–14 from ignition terminal 1 to control terminal 2, coolant 10–32°C. G8 ohms: 12–16, and that page prints no temperature window. Do not swap the two ranges.
- 5.G8: ignition off, disconnect the multi-way and expect P0201–P0206. Ignition on, the supply lamp on the ECM side must light. A dark lamp with an open fuse is a short to ground in the ignition feed, between the injectors and the fuse. A dark lamp with a good fuse is an open in that feed. Neither one is the control-pin test.
- 6.G8 control pin to B+ must stay dark. If it lights, short-to-ground test, then the ECM. The 2.6–4.6 volt check comes after that. Out of range: open/high resistance, then the ECM.
- 7.If the LY7 trio P0261, P0267, and P0273 is stored, test the shared ignition feed before three injectors are ordered.
- 8.Depressurize, and disconnect the battery before fuel is opened. The dollar pair is one injector. The wire, the fuse, and the ECM are outside it.
Repair cost
$768 – $953 (one fuel injector replacement, parts and labor, after the G3 or G8 circuit tests pass; the control wire, the bank feed, and the ECM are outside this pair)
The national RepairPal fuel-injector job, updated 3 September 2026, totals $768–$953, with labor $304–$446 and parts $464–$507. That is the printed pair, for the injector either chart replaces once the wiring has tested normal. Cylinder 3's access is not a separate line on the national average. A feed repair, a fuse, the LY7 bank wire, and an ECM are outside the pair. Diagnosis labor is $125–$183 and is separate. The 2026 Tucson injector line, $456–$604, is a different vehicle line and is not this pair.

DIY vs shop
Leave this one to a qualified shop. The barrier here is high-pressure fuel components, where residual pressure remains after shutdown and escaping fuel can penetrate skin. DIY attempts often produce a more expensive problem than the original code.
