Parts for your 2004 Suzuki Jimny-Throttle position sensors

2004 Suzuki Jimny Throttle Position Sensor (TPS)

Yes, the 2004 Suzuki Jimny uses a throttle position sensor. Factory documentation for the Jimny with the M13A 1.3‑litre petrol engine shows a TPS mounted on the throttle body and monitored by the engine control module. The Suzuki Jimny Service Manual (Engine Control/EC section, model years around 1998–2005) details TPS inputs and related DTCs (P0120–P0123), and common workshop data sets such as Autodata list the TPS as a key sensor for fuelling and ignition management. Suzuki’s parts catalogues for this model also include a throttle position sensor for the M13A throttle body assembly. That makes the TPS absolutely relevant on a 2004 Jimny.

On this Jimny, the TPS tells the ECU exactly how far the throttle plate is opened as the driver presses the pedal. That signal helps the ECU manage fuel delivery, ignition timing, idle control and emissions. On automatic models, TPS data is also used for shift timing and kickdown behaviour. When the TPS is healthy, throttle response is crisp, idle is steady and fuel economy stays on target. When it’s not, the Jimny can feel doughy off the mark, surge at light throttle or throw a check‑engine light with codes in the P0120–P0123 range.

There’s no set replacement interval for the TPS, it’s a “replace on condition” item. As part of routine servicing, it’s smart to:

• Inspect the TPS connector for corrosion, loose pins or broken insulation.
• Clean the throttle body (don’t drown the sensor in solvent) and ensure the throttle plate moves freely.
• Check for any stored or pending DTCs and live‑data smoothness from closed throttle to wide‑open throttle.

Replacement on the 2004 Jimny is straightforward: it’s typically a two‑screw, three‑wire sensor on the side of the throttle body. Mark the original position, swap the unit, and snug the screws evenly. Some versions allow slight rotational adjustment—aim for a smooth voltage sweep and correct base reading per the workshop spec. After fitting, clear fault codes and perform an idle learn (key‑on cycle and a short idle period, or as per the service manual). Use quality parts, avoid overtightening the plastic housing, and keep the wiring loom strain‑relieved.

Common clues it’s time to act include:

• Hesitation or flat spots when tipping into the throttle
• Unstable idle or stalling when coming to a stop
• Poor fuel economy and illuminated MIL with TPS‑related codes

Looked after properly, the TPS helps a 2004 Jimny run sweetly from the city to the back blocks, with smooth throttle response and predictable shifts.

Popular questions about 2004 Suzuki Jimny throttle position sensors

Does a 2004 Jimny actually have a TPS, and where is it?

It does. The sensor sits on the throttle body, opposite the throttle cable linkage on most M13A engines. It’s a small, black plastic unit with a three‑pin connector, reading the rotation of the throttle shaft so the ECU knows throttle angle at all times.

What symptoms point to a failing TPS on a 2004 Jimny?

Expect hesitation on light throttle, hunting idle, sudden surging, or delayed kickdown in autos. The check‑engine light may appear with codes like P0120–P0123. If the wiring and throttle body are fine, the sensor itself is often the culprit.

Does the TPS need calibration after replacement?

Many Jimny TPS units are slotted for minor adjustment. After installation, a quick base‑position check and an idle learn routine helps. Using a scan tool to confirm a smooth, linear throttle angle signal from closed to wide‑open is the safest bet.
